Problems solved by technology

[0002] The current biomass fuel boilers first need to process wood chips such as crushing, granulation, and drying, which consume a lot of electric energy and heat energy, and the combustion efficiency is low.
[0003] At present, there are also some biomass gas fuel boilers, but they are basically low in calorific value, the discharge of harmful chemical substances in low boiler flue gas exceeds the standard, and the thermal efficiency of the boiler is low.

Embodiment 1

[0030] Such as Figure 1-3 Shown: a biomass gas fuel steam boiler, which includes a burner 1, a boiler body 2, a flue gas duct 3, an economizer 4, an air preheater 5 and an outer frame 6.

[0031] The outer frame 6 includes a base, a steel frame and a platform ladder; it is installed on the boiler body 2 .

[0032] Such as Figure 4-6 As shown, the boiler body 2 includes a furnace wall 21, a steam-water generator 22 and a wall pipe 23; the furnace wall 21 is provided with a furnace 211 and a heat exchange chamber 212 arranged front and back, the so-called front-to-back arrangement can also be called a horizontal arrangement (horizontal arrangement) , instead of being arranged in the up and down direction, which can prevent the flue gas from flowing away quickly and make the heat energy not fully absorbed by the soda generator 22, which can improve the utilization rate of heat energy; the furnace 211 is separated from the front end of the heat exchange chamber 212 (near the bu...

Abstract

The invention discloses a steam boiler for biomass gas fuel. The steam boiler comprises a combustor (1), a boiler body (2), a gas duct (3) and an economizer (4), wherein the combustor (1) is arrangedon one end of a furnace wall (21) of the boiler body (2); the boiler body (2) comprises the furnace wall (21) and a steam generator (22); a hearth (211) and a heat exchange chamber (212) which are arranged front and back are arranged in the furnace wall (21), the front end of the hearth (211) is separated from the front end of the heat exchange chamber (212), and the rear end of the hearth (211) communicates with the rear end of the heat exchange chamber (212); the steam generator (22) is arranged in the heat exchange chamber (212) in the furnace wall (21); an ash removing door (213) is arranged on the side wall, close to the heat exchange chamber (212), of the furnace wall (21); and the gas duct (3) is connected with the heat exchange chamber (212) in the furnace wall (21) in a butt jointmode. According to the steam boiler, the heat value is high, the heat efficiency is high, the content of harmful chemical substances in the flue gas is low, the temperature of the emitted flue gas islow, and the effects of energy conservation and environmental protection can be achieved.

Description

technical field [0001] The invention relates to a steam boiler, in particular to a biomass gas fuel steam boiler. Background technique [0002] The current biomass fuel boilers first need to process wood chips such as crushing, granulation, and drying, which consume a lot of electric energy and heat energy, and the combustion efficiency is low. [0003] At present, there are also some biomass gas fuel boilers, but they are basically low in calorific value, the discharge of harmful chemical substances in low boiler flue gas exceeds the standard, and the thermal efficiency of the boiler is low. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a biomass gas fuel steam boiler, which has high calorific value, high thermal efficiency, low content of harmful chemical substances in flue gas, and low temperature of discharged flue gas, which can achieve energy saving and environmenta...
