Novel biomass cupola furnace

Abstract

The invention relates to cupola furnaces, in particular to a novel biomass cupola furnace. The novel biomass cupola furnace comprises biomass combustion furnaces, a horizontal furnace, a vertical furnace, a heat exchanger and a fan. A furnace burden storing and heating area is located in the center of the vertical furnace, the furnace wall surrounding the furnace burden storing and heating area isof a hollow structure, and the hollow structure in the furnace wall is used as a first high-temperature smoke area. The biomass combustion furnaces are provided with feeding inlets for biomass particles, and the biomass combustion furnaces communicate with the horizontal furnace through high-temperature smoke channels. A molten iron storage area and a second high-temperature smoke area are arranged in the horizontal furnace. A high-temperature smoke inlet of the heat exchanger communicates with the first high-temperature smoke area of the vertical furnace through a pipeline. A high-temperature smoke outlet of the heat exchanger communicates with blast orifices of the biomass combustion furnaces through pipelines, and the fan communicates with a blast orifice of the heat exchanger. According to the novel biomass cupola furnace, energy generated due to combustion of biomass particles is used, so that environmental friendliness and energy conservation are achieved; and in addition, wasteheat is well recycled and reused, heat efficiency is high, and service life is long.

Description

technical field [0001] The invention relates to an iron furnace, in particular to a novel biomass iron furnace. Background technique [0002] At present, natural gas cupolas and coke cupolas are common in the market. Natural gas cupolas use natural gas at a high cost, and natural gas cupolas do not have a good waste heat collection and utilization system, resulting in low thermal efficiency. Therefore, the cost of the furnace is high and the maintenance cost is high. [0003] The use of coke cupolas is easy to cause environmental pollution, and the thermal efficiency is low. There is also no good waste heat collection and utilization system, resulting in low thermal efficiency. Therefore, the cost of the furnace is high, the maintenance cost is high, and the service life is low. Contents of the invention [0004] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a new type of biomass iron furnace, whi...

Natural gas cupolas use natural gas at a high cost, and natural gas cupolas do not have a good waste heat collection and utilization system, resulting in low thermal efficiency, so the cost of the furnace is high and the maintenance cost is high

[0003] The use of coke cupola is easy to cause environmental pollution, and the thermal efficiency is low. There is also no good waste heat collection and utilization system, resulting in low thermal efficiency. Therefore, the cost of the iron furnace is high, the maintenance cost is high, and the service life is low.
