2. Furnace body framework: it is made of Q235 square tube of not less than 40*40mm.
3. Daily maintenance requirements: The cremator should meet the requirements of on-site maintenance and convenience, and there should be space operation requirements inside and outside to meet the daily maintenance and dust cleaning requirements of flue and secondary combustion chamber.
4. The burner for cremation machine is fully automatic, which requires electric ignition. The burner can automatically adjust the flame size, and the fuel supply should be automatically turned off when the ignition fails. Automatic ignition of main combustion and reburning is realized, and the fire resistance temperature of main combustion chamber and reburning chamber is above 1200℃.
5. Two-way tracked corpse-entering vehicle: The chain plate of the two-way tracked corpse-entering vehicle is convex, and the two sides of the bracket are equipped with packages lower than the chain plate, which can realize reciprocating motion, and can automatically transport and unload corpses without jamming clothes. When transporting objects exceeding the width of the track, the track will not idle or get stuck, and there is no need to preset the ground rail. The operation is simple, and the whole process of checking and entering corpses can be automatically completed by scanning the QR code.
6. Refractory material: the main furnace is made of phosphate firebrick or better material.
7. 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 ≥10 inches.

The information software management system in the funeral home should be interconnected and interlocked with the cremation equipment, and the control system of the cremation equipment can be controlled through the information software management system of the funeral home, for example, the information of the cremated remains can be provided through the information software management system (upper computer) of the funeral home, and the lower computer of the equipment receives instructions from the upper computer. Only the body designated by the upper computer can be cremated. If the body actually received by the lower computer does not match the body information sent by the upper computer, the cremation work should not be carried out normally and an error reason prompt will be given.
16. Intelligent combustion control technology can realize intelligent control of furnace temperature, pressure and oxygen content during cremation without manual intervention.
