Abstract
The invention relates to an air inlet device of a boiler combustion chamber. The air inlet device comprises a combustion chamber, wherein a partition board is arranged at the lower part of the inner part of the combustion chamber; a plurality of wave bulges are arranged on the partition board; an air hole is formed in the side surface of each bulge; a first one-way air inlet valve is arranged in each air hole; an air cylinder is arranged between the bottom of the combustion chamber and the partition board; a piston is arranged at the moving end of the air cylinder; annular gaskets matched with the inner wall of the combustion chamber are arranged on the side surface of the piston; and a second one-way air inlet valve is arranged at the bottom of the combustion chamber. When air inlet is required, the air cylinder is started to drive the piston to move upwards; the second one-way air inlet valve is started for air inlet, then the air cylinder drives the piston to move downwards to enable the entered air to be squeezed into the space between the piston and the partition board from the side surface of the piston, and then the air cylinder drives the piston to move upwards once again; and the first one-way air inlet valves are started to perform air inlet on the bottom of combustion substances. The air inlet device disclosed by the invention adopts an integral design, so that the assembling troubles are reduced, and the air inlet effect is guaranteed; and the air inlet device is simple in integral structure and low in cost.
