Built-in cremator heat exchanger

Abstract

The invention provides an internally-arranged cremator heat exchanger. The internally-arranged cremator heat exchanger comprises an air inflow pipe, heat exchange units, inner spray pipes and hot air spray pipes. The internally-arranged cremator heat exchanger is technically characterized in that the air inflow pipe is connected with a preheating pipe, the preheating pipe is arranged on the upper side of a vault of a hearth, the heat exchange units communicated with the preheating pipe through the inner spray pipes are arranged in the portions, on the two sides of the hearth, of a furnace body, the heat exchange units are hollow refractory prefabricated parts, the hot air spray pipes communicated with the hearth are arranged on the upper portions of the heat exchange units, and air outlets of the hot air spray pipes correspond to the middle of a bogie. The heat exchange units are the hollow refractory prefabricated parts, are directly laid inside the furnace body, and make direct contact with flames in the furnace body, and therefore the heat exchange temperature is high. Compared with a metal heat exchanger, the internally-arranged cremator heat exchanger is long in service life and free of oxidation corrosion, the expansion coefficient is consistent with that of the furnace body, and no damage is caused to the furnace body. Preheated air is further heated through the heat exchange units, the hot air temperature is higher, the incineration effect in the hearth is further improved, and fuel is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of cremation machine equipment, in particular to a built-in cremation machine heat exchanger. Background technique [0002] As we all know, a cremation machine is generally composed of a corpse delivery device, a combustion chamber, and a smoke exhaust device. A pit body is arranged in the combustion chamber, and a burner is arranged on the pit body. Quality, generally equipped with a heat exchanger, the heat exchanger is to heat the fresh air from the outside and send it into the combustion chamber to ensure sufficient oxygen and a certain pressure required for combustion, and prevent the cold air from directly entering the furnace to reduce the temperature in the furnace. Lead to incomplete combustion and high fuel consumption. The existing heat exchangers are all made of metal parts, and have defects in corrosion resistance and high temperature resistance, which cannot meet the requirements of the cremat...

AI Technical Summary

Problems solved by technology

The existing heat exchangers are all made of metal parts, which have defects in corrosion resistance and high temperature resistance, which cannot meet the requirements of the cremation machine, and the furnace body is often cracked or deformed due to inconsistent thermal expansion coefficients
