1.Removable double refractory incineration tray design-Two refractory incineration trays alternately enter the cremation chamber, one refractory incineration tray is cremated, the ashes are discharged and cooled, and the second refractory incineration tray can enter the furnace for cremation immediately.
Reduce cremation waiting time, reduce heat loss, and improve cremation efficiency.
2.Front loading and front cleaning-Contains two refractory incineration trays at the front of the furnace body. The front of the remains is loaded for cremation. The cremated ashes are loaded and cooled by the refractory incineration tray. The operator can pull the ashes with the refractory tray.
The front part of the combustion chamber, and then collect the ashes in the cleaning tray.
3.Automatic control-LCD touch screen, industrial PLC automatic control system makes operation simple and stable performance.
The microprocessor temperature controller with digital readout ensures the best control while providing the lowest energy consumption.
The LCD touch screen control panel provides visual verification of each stage.
The operator realizes automatic and automatic control of the board by turning the semi-manually controlled switch.
3.Flue Gas Waste Heat Utilization Design-First introduced by OY, this design allows the waste heat after combustion to be recovered through the waste heat device. The recovered waste heat is used to heat the combustion air, reduce fuel consumption, and extend the life of the furnace.
4.Double-layer loading door-It consists of an inner furnace door and an outer furnace door. The inner furnace door is made of stainless steel frame, filled with high temperature resistant aluminum silicate fiber, and can bear the high temperature of 1800℃ in the furnace.
