Cleaned briquette environment-friendly boiler

Abstract

The invention discloses a clean type coal environment-friendly boiler, which relates to the technical field of boilers. The coal storage chamber is set on the upper part of the combustion chamber, the combustion chamber is connected to the dust-reducing chamber through pipes, the dust-reducing chamber is connected to the first lower smoke box through the flue gas channel, and the first lower smoke box is connected to the second upper smoke chamber through the first return smoke pipe. The second upper smoke box is connected with the second lower smoke box through the second return smoke pipe, the second lower smoke box is connected with the first upper smoke box through the third return smoke pipe, and the first upper smoke box is connected with the fourth return smoke The pipe is connected with the third lower smoke box, the third lower smoke box is provided with a smoke outlet, and the auxiliary smoke port provided on the second upper smoke box is connected with the baffle in the flue gas converter through the pipe. The invention ensures continuous combustion after the boiler is shut down, completely solves the problem of smoke when the boiler is shut down, is energy-saving and environment-friendly, has strong practicability, is easy to popularize and use, and can also use bituminous coal and biomass fuels in addition to burning briquettes.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a clean type coal environmental protection boiler. Background technique [0002] At present, after the general boiler is shut down, in order to release the problem of flue gas emission caused by normal combustion in the furnace, the method generally adopted by various manufacturers is to open an auxiliary smoke port on the top of the coal storage room above the combustion chamber, and directly enter the chimney through the flue When the induced draft fan is stopped, the original reverse burning method becomes normal combustion, and the normal combustion method will produce a large amount of smoke, which contains a lot of unburned carbon black and dust. Direct discharge, one is polluting the environment, the other is energy waste, the manufacturer has not yet solved the problem of smoke from the shutdown of the boiler, based on this, it is still necessary to design a new type of c...
