A more energy-efficient, environmentally friendly, and high thermal efficiency reciprocating grate combustion device.

　　Currently, in some regions of our countryReciprocating grateThe boiler utilization rate is relatively high. In existing technology, the common internal structure of the reciprocating grate is sloped, which has a large space but a high air leakage coefficient, leading to low combustion efficiency, easily causing unburned fuel, incomplete combustion, high fuel consumption, and incomplete combustion can also produce black smoke, causing environmental pollution and low thermal efficiency.

　　To solve the above technical problems, technicians provide a reciprocating grate combustion device that burns fully, does not pollute the environment, and has high thermal efficiency. To achieve the above objectives, it adopts the following technical scheme: a reciprocating grate combustion device, including a combustion chamber, a feeding hopper, a reciprocating grate, a front arch, a rear inclined arch, a rear arch, a primary air inlet, a fire wall, and a smoke wall,Reciprocating gratewhich is inclined and set on the lower side of the combustion chamber. The outlet of the feeding hopper is set at one end of the reciprocating grate, and a passage is set between the lower end of the fire wall and the reciprocating grate. The upper end of the smoke vertical wall is fixed on one side of the lower end of the fire wall and extends to the passage between the fire wall and the reciprocating grate. The other side of the fire wall is connected to one end of the rear arch, and the other end of the rear arch is connected to the heat-insulating wall of the combustion chamber. The side walls of the combustion chamber, front arch, and rear inclined arch are equipped with secondary air blowing pipes.

　　Among them, the air inlet of the secondary air blowing pipe is connected to the dispersion pipe, and the air inlet of the dispersion pipe is connected to the secondary air blowing mechanism. The side wall of the combustion chamber is equipped with a furnace door, which is set on the upper side of the grate. The grate is equipped with multiple through holes. The upper part of the furnace body is equipped with an igniter, and the ignition end of the igniter is equipped with a material blocking plate. The upper half of the furnace body is equipped with a water jacket, which has an inlet and an outlet, and the water jackets between the two furnace bodies are connected by a connecting pipe. The furnace body is also equipped with a blower. The bottom of the furnace body is equipped with a slag discharge ball.

　　There are ash discharge ports on the rear inclined arch and the rear arch, and a cleaning mechanism is set on the ash discharge port. There is a sand powder nozzle between the rear inclined arch and the reciprocating grate. Steel frames are installed inside the front arch, rear inclined arch, rear arch, and fire wall. There is a smoke outlet between the front arch and the rear inclined arch, and the smoke outlet is equipped with a temperature measurement port and a nitrogen fire extinguishing port.

　　Compared with existing technology, the advantages of this reciprocating grate combustion device are: when the fuel entersReciprocating grateand is brought into the combustion chamber by the reciprocating grate, the combustion chamber is surrounded by the front arch, rear inclined arch, fire wall, smoke wall, and side walls. The fire wall and smoke wall at the rear of the combustion chamber slightly block the fuel, allowing the fuel to burn fully, releasing heat fully, and concentrating heat reflection; at the same time, due to the reasonable layout of the device, it avoids problems such as unburned fuel, incomplete combustion, high fuel consumption, and black smoke, providing sufficient combustion air with primary and secondary air, improving combustion efficiency, reducing dust emissions, and enabling efficient combustion of fuel in the reciprocating grate.
