Problems solved by technology

[0002] The tail gas discharged from the boiler combustion often contains a lot of heat, if the heat is not recovered immediately, it will easily cause energy waste
[0003] As boiler fuel, natural gas has the characteristics of high combustion efficiency and sufficient combustion; while ethanol is liquid at room temperature, when ethanol fuel is supplied in the furnace, it cannot enter in the form of gas like natural gas, so it is easy to cause uneven combustion in the boiler. phenomenon, so there are not many boilers using ethanol as fuel

Abstract

The invention discloses a horizontal natural gas combined fuel boiler. The horizontal natural gas combined fuel boiler comprises a main boiler body and a tail gas heating boiler body. The exhaust endof the main boiler body communicates with the hot smoke inlet end of the tail gas heating boiler body through a hot smoke guide pipe. A cold water guide-in pipe and a hot water guide-out pipe are further included. The cold water guide-in pipe communicates with the water inlet end of the tail gas heating boiler body. The water outlet end of the tail gas heating boiler body communicates with the water inlet end of the main boiler body through a transition water pipe. The water outlet end of the main boiler body communicates with the hot water guide-out pipe. The horizontal natural gas combined fuel boiler is simple in structure, and liquid ethyl alcohol is converted into ethyl alcohol steam to be combusted together with natural gas.

Description

technical field [0001] The invention belongs to the field of boilers, in particular to a horizontal natural gas combined fuel boiler and a working method thereof. Background technique [0002] The tail gas discharged from boiler combustion often contains a lot of heat, and it is easy to cause energy waste if the heat recovery is not carried out immediately. [0003] As boiler fuel, natural gas has the characteristics of high combustion efficiency and sufficient combustion; while ethanol is liquid at room temperature, and when ethanol fuel is supplied in the furnace, it cannot enter in the form of gas like natural gas, so it is easy to cause uneven combustion in the boiler. phenomenon, so there are not many boiler equipment that use ethanol as fuel. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a fully heated horizontal natural gas combined fuel boiler. [0005] Technical...
