Biomass combustion heat exchange composite integrated furnace

Abstract

The invention discloses a heat transfer compounding integrated furnace for biomass burning. The furnace comprises a steam boiler, a smoke vent of the steam boiler is sequentially communicated with a hot blast heater and a hot water furnace, the hot water furnace is communicated with a flue gas emission and flue gas waste heat recycling device, one fan is needed by whole equipment, therefore the production cost can be saved; furthermore, the smoke exhaust way of a traditional flue can be changed by the flue gas emission and flue gas waste heat recycling device, so that energy saving can be realized, and the dynamics of environmental protection can be improved; in addition, by adopting the scheme provided by the invention, the heat transfer compounding integrated furnace is novel in structure, convenient and quick to ignite, safe and convenient for fuel transportation and high in heat efficiency, and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to a clean combustion gasification boiler using biomass briquette fuel, in particular to a biomass combustion heat exchange composite integrated furnace with multiple functions, which belongs to the technical field of environmental protection equipment. Background technique [0002] At present, energy and environmental issues have become the focus of global attention. Although oil, coal and natural gas are still the main sources of fuel, with the depletion of fossil energy and the increasingly serious environmental problems, the development and utilization of clean and renewable energy has become an important issue. pressing issues. [0003] Biomass energy, as an important part of renewable energy, has attracted widespread attention. As a large agricultural country, my country has a huge annual output of biomass energy, so its development potential as a renewable energy source is huge and the prospect is broad. [0004] Biomass ...

AI Technical Summary

Problems solved by technology

[0011] However, the biomass briquette fuel furnaces currently on the market generally have the following defects: first, low thermal efficiency, inconvenient ignition, unstable combustion, and poor heat transfer; second, the flue gas removal temperature is too high, wasting energy and polluting the environment

[0012] The third is that the manual shovel filling method is still used for material delivery, which is time-consuming, laborious and costly;

[0013] Fourth, most of the flues used for exhausting smoke are equipped with induced draft fans, and a blower connected to the furnace is installed on one side of the furnace body, and the smoke is exhausted in the traditional way of leading in front and blowing in the back; two sets of equipment are required, which increases the working cost;

[0014] Fifth, most of the traditional flue adopts the center-ejection smoke exhaust method, which has the disadvantages of small flue gas flow rate and low furnace negative pressure
