4. Furnace door: the thickness of the furnace door is ≥100mm, the main material is made of high-temperature resistant aluminum silicate cotton/board, and the exterior is decorated with stainless steel, the thickness of which is not less than 1 mm. It has the function of emergency manual operation and can easily open and close the furnace door. The frame is stable, the oven door is horizontal, the oven door lifting stroke is accurate, the combined transmission is low noise, and the continuous opening and closing is trouble-free.
5. Body conveying system: ① Two-way tracked corpse conveying vehicle is adopted, which runs smoothly. After the coffin is conveyed into the furnace, it exits the furnace to ensure that the high temperature will not damage the transmission of the car body under the condition of high frequency use. ② The corpse entry system should be able to realize the dual operation functions of manual operation and automatic one-button operation. ③ The corpse entry operation has automatic and manual operation, and the operation panel is LCD screen. Manual operation can be realized in case of emergency (power failure, local transmission failure).
6. Combustion system:
① The main combustion chamber is made of high-quality materials with high temperature resistance above 1300℃, and the vault of the furnace is made of high-temperature prefabricated parts. The chamber hot air is equipped with an air valve, which has good sealing performance, no air leakage and flexible opening and closing.
② The left and right sides of the furnace are equipped with combustion-supporting air ducts made of high-temperature resistant materials.
(3) The main combustion chamber is equipped with high-quality burners, which are automatically ignited to achieve uniform and full combustion.
④ The burner should be equipped with flameout protection device, which can ensure the correct ignition procedure of the burner, such as automatically turning off the fuel supply when the ignition fails.
⑤ The masonry technology of the combustion chamber should meet the requirements of sealing, heat preservation, firmness and emergency security of the combustion chamber.
⑥ The retention time of flue gas in high temperature area should be more than 2 seconds.
⑦ When the oven door is opened, the automatic control system should meet the requirements of slight negative pressure in the furnace, and the smoke will not escape. The small oven door is electrically controlled, with safety protection measures and high sealing performance.
⑧ The temperature and pressure of the main combustion chamber and the reburning chamber should have over-limit protection and explosion-proof devices.
7. Air supply system: The overall air supply system should have a reasonable layout and smooth pipeline, and the air volume can be automatically adjusted. The automatic air valve should be stable in operation without mechanical failure. In case of failure, manual and automatic control should be switched for a short time to complete cremation. During combustion, the combustion-supporting air should have a preheating device to meet the requirements of energy saving, emission reduction and energy consumption reduction, and the air supply system should have a waste heat utilization device during design. Blower, induced draft fan, oven door motor, corpse car motor and flue gate motor need to be equipped with over-current and short-circuit protection devices, and equipped with sound insulation measures to ensure good heat dissipation and low noise operation.
8. Electric control system in front of the furnace: controlled by industrial programmable controller (PLC) module, with man-machine interface, operating screen resolution ≥1027×768 and size ≥8 inches.
9. Electric control system after furnace: industrial programmable controller (PLC) module is used for control, and the man-machine interface is used for operation. The resolution of the man-machine interface display screen is ≥1027×768, and the size is ≥12 inches.
10. All kinds of electromagnetic valves, sensors, limit switches and other parts required for electric control before and after the furnace are selected from national standard products.
11. The front and rear halls are controlled by touch screen. If the touch screen fails, it will not affect the normal use of the equipment.
Emergency operating system: equipped with two independent operating systems.
12. Electrical control cabinet: It has the functions of overload, short circuit, high temperature resistance and comprehensive control of the system. The electrical control system can realize simple installation, which is different from the traditional installation site to connect all the electrical appliances and realize plug and play.
13. Thermal insulation material: Aluminum silicate cotton with good thermal insulation and thermal insulation performance is used around the furnace body, and the thickness is not less than 180mm.
14. Air preheater: it must be installed on the top of the furnace vault, heated by radiation, and its service life is more than three years. Refuse to embed the flue. The material is not less than 022Cr17Ni12Mo2, and the thickness is not less than 5mm.
15. The side of the cremator door shall be provided with an auxiliary flue to ensure that there is no smoke when the door is opened.
16. Smoke exhaust system: environmental protection ejector low chimney is adopted for exhaust, and the ejector chimney is made of stainless steel plate not less than 3mm, and the first section buried underground is made of stainless steel with a thickness not less than 4 mm.. The smoke exhaust system shall be operated by one-button switching with the exhaust smoke exhaust system.
17. Daily maintenance requirements: The cremation machine shall meet the requirements of on-site maintenance and convenience, and the internal and external space shall meet the requirements of daily maintenance and operation, and meet the requirements of cleaning up the accumulated ash in the flue and secondary combustion chamber.
