Human cremator performance features

Nearly every cremation oven manufacturer of standard size human cremators is recommending a 30 minute cool-down between cremations to prevent overheating and emissions smoke from the stack. Cremation Equipments cremation oven model with it’s advanced cremator operating system that automatically controls the combustion rate so that extended cool-down between consecutive cremations is not necessary. Eliminating cool-down results in faster cremation cycles, longer refractory life and can reduce fuel usage by up to 55% on the second and successive cremations of the day.

High performance human cremator

High performance cremator duty insulation, an improved drafting system along with a cremator operating system that monitors and controls the oven chamber temperatures by adjusting firing rate of the burners and the combustion air supply enables the human cremation furnace to operate around the clock. If necessary in emergency situations or during periods of peak demand without generating visible emissions or smell.

Human cremator to cremate

The cremator uses a Programmable Logic Controller (PLC) automatically controls the firing rate of the cremator burner and combustion air supply to the primary chamber to maintain a optimal operating temperature. This prevents an excessive combustion rate in large and obese cases that can lead to overheating, fluid problems and visible emissions. This human cremator can accommodate cases up to 1000 lbs.

Cremate up to seven bodies in 10 hours

This human cremator is eliminating the cool-down along with a fast cremation cycle allows crematories for a greater daily efficiency. The cremator can consistently cremate up to seven normal size bodies in ten hours and outperforms all other human cremators in it’s price and size.

Cremator OMR system

The cremation ORM Operating, Monitoring, Reporting is operating and controlling the cremation system so the operator is informed about the cremation process. Standard to this cremation oven is a proven and tested automatic operating, monitoring and report system with colour touch screen control as standard. Load the body and container in the primary chamber, set the timer and press the Start button to begin the cycle. The system is programmed to begin a purge cycle before igniting the secondary cremation oven chamber burner to start the preheat cycle. Once the proper temperature is reached in the pollution control chamber the primary burner is ignited to begin the cremation cycle. After completion of the cremation the cremation system advances to the cool-down cycle at which time the burners shut down and clean out of the cremated remains is possible.

Cremation control system eliminates emissions

A complete combustion is achieved in the cremators temperature controlled in the large secondary chamber. Greater than 99% of volatilized carbon is created in the cremation process is converted to carbon dioxide (CO2). In addition, a sensor is located at the base of the stack to monitor the clarity of the exhaust gases. Once the exhaust gases reach 15% opacity the PLC automatically shuts down the primary burner and adjusts the air supply for a better combustion to slow the combustion rate and prevent visible emissions from exiting the stack.

Quiet cremator no noise cremations

The combustion air blower and motor assembly are shrouded with an acoustic sound deadening material that substantially reduces the level of noise of the cremator when it’s in full operation. This allows placement of the cremator next to a high traffic area without disruptance.

Cremator has advanced combustion system

The number and size of the air ports in the primary cremation chamber have been increased to supply more air for a better combustion when the cremator is operating and in a production mode. While fresh air is necessary for the cremation combustion it also can act as a cooling effect to control the rate of combustion. This human cremator is equipped with a refractory lined draft inducer. Air injected into the inducer creates a constant negative pressure in the primary chamber to improve air flow into the secondary chamber and on into the stack. This enables the operator to remove the cremated remains from the primary cremation chamber following the cremation cycle as the hot air flows away from the open charging door to the front or rear of the cremation oven. As extra benefit, the hot exhaust gases pass through the secondary chamber into the draft inducer they are cooled reducing the exit temperature of the hot gases into the atmosphere in half.

Cremation oven equipment features

The cremator has an power charging on hydraulics
Most manufacturers use a single hydraulic cylinder and a series of chains and sprockets to raise and lower the door. Unfortunately, a low fluid level, leak in the hydraulic fluid line, or a break in the chain during operation can lead to an unsafe condition where the heavy door would fall. To reduce this risk these same manufacturers have installed a manual door stop that is engaged when the door is in the fully open position. Despite this safety measure it will not prevent the door from falling when the door is raised or lowered. Cremation Equipments utilizes hydraulic cylinders to raise and lower the door. No chains are used and a manual door stop is not required as the heavy door will lower very slowly if there is a failure in the system.

Cremator view port
Standard to the cremator is a view port located in the power charging door. This allows the operator to visually observe the status of the cremation. Since the cremation cycle is based on a time setting, the operator has the option of reducing time, adding time or advancing to the next cycle depending on the stage of the process. Raising the door to check on the status during the combustion process exposes the operator to radiant heat or possible flashback.

Cremator temperatures 3000 °F
In cremation furnace design the primary or cremation chamber is located directly above the secondary or pollution control chamber. The floor or hearth of the cremation chamber serves as the roof of the secondary chamber. Environmental regulations generally require the secondary chamber temperature to be maintained at 1600° F (872 C°) and the gases retained for at least one second before exiting the chamber. This temperature and residence time is necessary to assure complete combustion and to prevent smoke or smell from being emitted from the stack.

During the preheating of the secondary chamber as well as during the cremation process, heat transfers through the roof of the secondary chamber to the floor and walls of the cremation chamber creating a “hot hearth effect”. There are two distinct advantages to this fuel efficient design. One is that it lowers fuel consumption by utilizing heat generated in the hotter secondary chamber to enhance the combustion process in the cremation chamber. Secondly, a hot hearth vaporizes fluids released from the body during cremation more quickly so they burn off rapidly and do not collect on the floor. This is particularly important when cremating very large caskets that contain large amounts of body fats and fluids.

In cold hearth units the secondary chamber is located above or at the rear of the cremation chamber. None of the heat generated in this chamber is efficiently utilized to heat the cremation chamber. Is creates a too rapid release of fluids, particularly in large and obese cases can result in a fluid build up on the floor. Since the fluids cannot vaporize or burn off fast enough there is a potential for the hot excess fluids to flow through the loading door creating a fire hazard. Cremation Equipments has the best crematory solutions.

Cremator programmable logic controller PLC

The proven PLC operating system monitors, controls and reports the chamber temperatures, combustion air supply and timing cycles for purging, preheating the pollution control chamber, cremation and cooling down cycles. The PLC system is fully automatic requiring the operator to simply select the time for the cremation cycle and press the start button to begin the cremation cycle. Once the secondary chamber is preheated the system automatically advances to the next cycle without operator involvement through shut down.

While the PLC is programmed at the factory and checked at start-up the standard program. Does allow crematories for changes to be made in temperature set points, timing of cycles and combustion air adjustments if necessary. The colour touch screen allows the operator to visually check each stage and status of the process including chamber temperatures, combustion air, time and burner operations during the cremation.

Cremator control touch screen

Standard to all our cremator models is a colour touch screen that displays the status of the process through various screens available to the operator. Door, Start and Stop controls are on the main screen. Other screens display burner operation, chamber temperature, temperature set points, time as well as other cremator functions. The touch screen is mounted at eye level and can be positioned from 0 to 180 degrees for easy viewing. Through the various screens, the operator can monitor many functions as well as exercise more control over the process.

Cremator appearance

As it becomes more popular to view the body or casket being placed in the cremator and families are requesting to see the cremation equipment and crematory prior to cremations, the overall appearance of the cremation equipment is important. The cremator has been designed to be a innovative a modern design. The exterior wall and front panels are finished in a dark grey powder coat finish and trimmed in stainless steel. The cremation oven door and ash compartment drawer are clad in stainless steel. All major components are housed in the end of the compartment away from the view.

Cremator service compartment

The cremator service compartment houses nearly all the important components such as the power for the hydraulic door motor and pump, secondary burner, fuel and air regulators, combustion air blower and motor and electrical panel. These components are easily accessible for routine service and maintenance and the location of the service compartment minimizes noise levels during a cremation process.

Cremator easy ash tray clean out

The cremator has a front loaded ash clean out tray or ash unit. After completion, of the cremation the door can be partially raised and with the clean out rakes and steel cremation brushes provided, the cremated remains are pulled toward and through the door opening where the cremated remains fall through a chute integral to the unit and into the ash clean out tray. The ashtray is large enough to collect all the cremated remains. Fabricated of heavy duty aluminium and clad in stainless steel, the ash tray can also be used as a cooling compartment for the hot cremated remains while the next cremation is in cremation progress.

Cremator fuel efficiency

The most fuel efficient cremation machine in the cremation industry. As the cost of fuel continues to escalate fuel consumption has become a critical issue in the operation of a crematory. We have been able to verify that the fuel efficiency of the cremator is superior to other cremation equipment units in the worldwide market. There are several variables in fuel efficiency such as preheat time, number of consecutive cremations, weight and size of the body, cremation time, and quality of the cremated remains. Once combustion starts and as heat is absorbed into the refractory walls, roof, and hearth the body becomes it’s own fuel and proper operating temperature can be maintained by controlling the combustion air.

The pre-heating time must always be included in fuel usage for the first cremation of the day. Cremations require less time depending on how much cooling down is allowed. Most cremators require a minimum of half an hour up to one hour cooling down in order to remove the cremated remains and to prevent the cremator from overheating and visible emissions during the next cremation. The cremator requires no cooling down and will not generate emissions due to overheating. This is a unique feature of the cremation control system results in fuel savings when performing seven several cremations per day.

Eliminating the cremators cooling down can save about 55-65 precent of the fuel usage for the next cremation. The primary and secondary chambers remain hotter and this can shorten the cremation period by as much as 15%. By the third consecutive cremation the secondary burner is firing mostly at low-fire and chamber temperatures are maintained primarily by controlling combustion air. Keep in mind this is being accomplished without emitting cremation emissions common in other cremation units. This human cremator will cremate up to seven bodies in 10 hours with an average cremation time of between 60-90 minutes.

A cremation is only completed when there is no black ash and the cremated remains are white and very brittle. There is a lot of variation between bodies and the way they burn. The muscle mass, fat content and even health issues prior to death will affect the combustion process. The cremation control system is programmed to automatically adjust for these differences to cremate a human body in a cremation oven / furnace.
