Embodiment Construction

[0015] like figure 1 and figure 2 As shown, the high-moisture fuel steam boiler is composed of a boiler body 1, a feeding device 2, a furnace 3, a grate 4, a pre-combustion chamber 5, an economizer 6, a preheater 7, and a gasification burner 8.

[0016] A pre-combustion chamber 5 is designed at the front of the boiler body 1. The pre-combustion chamber 5 is located in front of the furnace 3 and above the reciprocating grate 9 with a large inclination angle. The inlet of the pre-combustion chamber 5 and the outlet of the feeding device 2 Connected. The pre-combustion chamber does not have a heating surface, and is made of refractory bricks and refractory concrete. This thermal insulation design can generate a lot of radiant heat around the pre-combustion chamber when the fuel is pre-combusted, and further strengthens the drying and drying of high-moisture fuel. pre-ignition. The high-moisture fuel is fed to the pre-combustion chamber 5 through the specially designed feeding...

Abstract

The invention discloses a high-moisture fuel fired steam boiler. The high-moisture fuel fired steam boiler comprises a boiler body, a combustion cavity and a feeding device, a pre-combustion chamber is arranged in front of the combustion cavity and communicated with a vaporizing combustor outside the boiler body, a discharging port of the feeding device is communicated with a feeding port of the pre-combustion chamber, and a high-inclination-angle reciprocal grate is arranged below the pre-combustion chamber. High-moisture fuel in the pre-combustion chamber is dried by high-temperature smoke generated by the vaporizing combustor and then fed to a central combustion area of the combustion chamber for combustion, and consequently completeness in fuel drying is realized, and fuel burn-off rate is increased.

Description

technical field [0001] The invention belongs to the technical field of boilers, and in particular relates to a steam boiler suitable for burning high-moisture biomass fuel. Background technique [0002] After years of research and development, biomass fuel boilers have been widely used in the field of industrial boilers, but the moisture content of biomass fuels used by almost all biomass fuel boilers is about 10%. Design a suitable boiler furnace type, and high-moisture biomass fuels, such as dregs with a water content of more than 60%, are used in large quantities in the pharmaceutical and beverage industries. Therefore, it is necessary to design and develop boilers suitable for high-moisture biomass fuels. necessary. SUMMARY OF THE INVENTION [0003] In order to solve the problems existing in the prior art, the present invention provides a steam boiler suitable for high-moisture fuel combustion. [0004] In order to achieve the above purpose, the technical scheme adop...
