Automatic temperature control lower reverse combustion type coal-fired boiler

Abstract

The invention discloses an automatic temperature control lower reverse combustion type coal-fired boiler. The automatic temperature control lower reverse combustion type coal-fired boiler comprises a boiler body, a water heating layer, a coal feeding inlet, an ash outlet, a smoke outlet, a waste heat water tank, an electrical appliance protective cover, an observation opening, an automatic reciprocating grate and a linkage arm, wherein the water heating layer is arranged around the boiler body, a heat flow buffer chamber is formed by the water heating layer in the boiler body, the waste heat water tank is arranged outside the water heating layer, and a lower reverse combustion heating pipe is arranged in the boiler body; the automatic reciprocating grate is arranged in the boiler body, an upper combustor is arranged above the automatic reciprocating grate, a lower combustor is arranged below the automatic reciprocating grate, and a temperature sensor is arranged on the boiler body. According to the structure of the automatic temperature control lower reverse combustion type coal-fired boiler, the upper combustor and the lower combustor are formed so as to achieve the purpose of complete combustion, combustion can be conducted for 3-5 days when a coal storage bin is filled with coal, fire banking can be conducted for seven days, the temperature is automatically controlled, the automatic acousto-optical indication is given when coal deficiency exists, ash falls off through the automatic reciprocating grate, drinkable hot water can be obtained for a long time, thermal efficiency is high, the temperature rise is rapid, installation and maintenance are convenient, and the automatic temperature control lower reverse combustion type coal-fired boiler is applicable to civil heating and heating for small enterprises.

Description

technical field [0001] The invention relates to the field of heating boilers, in particular to a reverse-fired coal-fired boiler under automatic temperature control. Background technique [0002] As people become more and more aware of energy saving and emission reduction, they have higher requirements for the hygiene and comfort of the living environment. The original old-fashioned boilers have large fuel consumption and low automation, which has brought great impact on technology, economy, society and benefits. influence, such as Figure 4 , the old-fashioned boiler is added with coal, and it will burn simultaneously in the combustion chamber 52, and the combustible gas and sulfur dioxide will be discharged from the smoke outlet 50 together with the heat flow, and the coal core combustibles will fall into the ash storage chamber 54 and will not burn, and the smoke outlet 50 will emit black smoke , is a common thing, can not achieve complete combustion, the water jacket 51 ...

[0002] As people become more and more aware of energy saving and emission reduction, they have higher requirements for the hygiene and comfort of the living environment. The original old-fashioned boilers have large fuel consumption and low automation, which has brought great impact on technology, economy, society and benefits. influence, such as Figure 4 , the old-fashioned boiler is added with coal, and it will burn simultaneously in the combustion chamber 52, and the combustible gas and sulfur dioxide will be discharged from the smoke outlet 50 together with the heat flow, and the coal core combustibles will fall into the ash storage chamber 54 and will not burn, and the smoke outlet 50 will emit black smoke , is a common thing, can not achieve complete combustion, the water jacket 51 is mostly above the furnace bottom 53, the heat loss is large, there are many coal nuclei, the soot leaks outside, it is neither hygienic nor environmentally friendly, there is a lot of soot on the inner wall, and it absorbs heat for a long time Volume drop, increased fuel and other disadvantages
