A progressive smokeless combustion furnace

Abstract

The invention discloses a progressive smokeless combustion furnace. The progressive smokeless combustion furnace comprises a furnace body. A partition wall and a fixing fire grate are arranged in the furnace body. The top end and the two side edges of the partition wall are correspondingly fixed to the inner wall of the furnace body, a movable baffle capable of sliding along the partition wall is arranged at the bottom end of the partition wall, the furnace body is divided into a fuel bin and a combustion chamber through the partition wall, the fixing fire grate is located below the fuel bin and obliquely arranged, a charging port communicated with the fuel bin and a waste exhaust port communicated with the combustion chamber are formed in the upper end of the furnace body, an opening communicated with the fuel bin and the combustion chamber is formed between the movable baffle and the fixing fire grate, an ash falling bin is arranged at the lower end of the fixing fire grate, a primary air inlet communicated with the ash falling bin and a secondary air inlet communicated with the combustion chamber are formed in the side wall of the furnace body, and a plurality of secondary air nozzles are arranged in the positions, corresponding to the secondary air inlet, in the combustion chamber. Combustion is sufficient, no black smoke is discharged in the initial stage, intermittent burning and adjustable strength can be achieved, ash removing is automatic, and resource waste and environment pollution can be reduced.

Description

technical field [0001] The invention relates to the field of combustion furnaces, in particular to a progressive smokeless combustion furnace. Background technique [0002] At present, combustion furnaces are widely used, and the furnace combustion in the prior art mainly has the following problems: [0003] 1. The initial exhaust smoke is large, mostly black smoke, which is very serious to environmental pollution; [0004] 2. The loss of smoke exhaust is large and the combustion intensity is not easy to control during the combustion process, resulting in waste of resources; [0005] 3. Slow start and cannot achieve sustainable combustion; [0006] 4. Manual cleaning means a waste of manpower and safety cannot be guaranteed. SUMMARY OF THE INVENTION [0007] In order to solve the above technical problems, the present invention provides a progressive smokeless combustion furnace, which has no black smoke at the initial stage of combustion, adjustable combustion intensity...
