Single-drum double-furnace composite combustion settling chamber angle tube boiler

Abstract

The invention discloses a single-drum double-furnace composite combustion settling chamber angle tube boiler. The single-drum double-furnace composite combustion settling chamber angle tube boiler comprises a boiler body part and a combustion system part, wherein the boiler body is internally provided with a support structure and a double-furnace structure; the support structure comprises a vertically arranged front side support downtake pipe, an intermediate support downtake pipe, and a rear side support downtake pipe; the upper end of the front side support downtake pipe is connected with adrum, and the lower end of the front side support downtake pipe is connected to side water wall lower receiving boxes; two ends of the intermediate support downtake pipe and the rear side support downtake pipe are respectively connected with side water wall upper receiving boxes and the side water wall lower receiving boxes; the drum is arranged on the upper portion of one side of the boiler body;the drum is connected to a water inlet pipe; the bottom of the drum is connected to a first downtake pipe and a second downtake pipe communicating with the intermediate support downtake pipe and therear side support downtake pipe; and the double-furnace structure is composed of a first furnace and a second furnace. The single-drum double-furnace composite combustion settling chamber angle tube boiler has the advantages that the support strength is high, and the structure is stable, so that the biomass fuel is dried in the furnace, the fuel is directly bundled and fully burned, the nitrogen oxide emissions are reduced, the energy is saved and the environment friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular, it can meet the discharge requirements of the national boiler air pollutant discharge standards, and solve the problems of high moisture content, low calorific value, inability to burn directly, insufficient combustion, serious slagging, and nitrogen oxidation after bundling biomass. A single-drum double-hearth composite combustion settling chamber corner tube boiler with high emission concentration and polluting the environment. Background technique [0002] As we all know, with society's increasing demand for energy, fossil fuels as the main energy source are rapidly decreasing. Therefore, looking for a renewable alternative energy source has become the focus of widespread concern in society. Biomass energy is an important renewable energy, which has the characteristics of green, low carbon, clean and renewable. Accelerating the development and utilization of biomass energy has...

Problems solved by technology

However, currently biomass boilers generally have high water content and low calorific value in terms of the use of biomass fuel and boiler structure. However, existing boilers cannot bundle and directly burn biomass fuel with high water content. It can be burned after the water is dry, which increases the cost of use, insufficient combustion, and serious slagging; the boiler has low strength and weak support, which is easy to cause safety accidents; there is no settling chamber, the dust cannot settle, the concentration of nitrogen oxides is high, and the thermal efficiency of the boiler is low.
