Detailed Description

When the secondary air inlet furnace is assembled, the furnace lining (2) is firstly arranged in the secondary air inlet environment-friendly furnace shell (1), then the miniature compressed air pump (9) is connected to the air distribution valve (8) through an air pipe, the air supply pipeline (6) arranged on the air distribution valve (8) is connected to the secondary air inlet (5), the air supply pipeline A (7) arranged on the air distribution valve (8) is connected to the bernoulli atomizing nozzle (10), and the power plug is connected with a power supply, so that the complete secondary air inlet furnace is assembled.

When the device is used, the ignition firewood is firstly placed on the fire grate (13) for ignition, then the coal is placed on the ignited ignition firewood, the atomization water tank (14) is filled with atomization water, and simultaneously the water is injected into the required water quantity through the water injection port (17) of the hot water tank according to the requirement. After the coal is completely ignited, a timer (15) is started once every time coal is newly added. When the timer (15) is powered on, the miniature compression pump (9) starts to work, air with certain pressure is divided into two paths through the air dividing valve (8), one path enters the secondary air inlet (5) through the air supply pipeline (6), then enters the combustion chamber (18) in the furnace through the secondary air inlet outlet (4) through the secondary air inlet annular air passage (3), insufficient oxygen is supplemented in the combustion process, so that the combustion in the chamber is more sufficient, the gas generated by the miniature compression pump (9) is connected to the Bo-Ding nozzle (10) through the other air supply pipeline A (7), because the gas flow rate of the compression pipeline is very high, the water in the atomization water supply pipe (19) is atomized by the Bo-Ding nozzle (10) and then is blown into the chimney (12), and the atomized water beads are mixed with harmful gas and dust generated in the combustion process to generate larger particles which are deposited at the bottom of the smoke pipe, thus, the flue gas discharged outside is purified.
