Abstract
The utility model discloses a methane-coal dual-burning air heating furnace, which comprises a furnace body, and is characterized in that the furnace body is provided with a burning unit and a heat exchanger, wherein the burning unit comprises a hearth, the hearth is provided with a methane burner access entry and a fire coal refueling port, the bottom of the hearth is provided with a fire grate, a fire coal slag hole is arranged under the fire grate, the heat exchanger comprises a plurality of layers of heat exchange tubes, each baffle is arranged between every two adjacent layers of heat exchange tubes, a cold air inlet is arranged on the side of the heat exchange tube at the bottom layer, a hot air outlet is arranged on the side of the heat exchange tube at the top layer, a refractory layer is arranged on the inner wall of the furnace body, and the top of the furnace body is provided with a chimney. Compared with the prior art, the air heating furnace has the advantages that due to the arrangement of the plurality of layers of the heat exchange tubes, the heat generated by the combustion of methane can make contact with the furnace wall in a large area for a long time, thus the heat exchange time is prolonged, the utilization efficiency of the methane is greatly improved, and the temperature of flue gas emissions is reduced.
Description
Technical field
The utility model relates to a kind of biogas and coal two burns hot-blast stove.
Background technology
Biogas is a kind of mist, can burn for cooking, dry agricultural byproducts, heating, illumination and production utilization etc.The big-and-middle-sized biogas engineering of China starts from 1936, and after this, production and the scope of application of biogas have been widened in the foundation of big-and-middle-sized waste water, aquaculture sewage, villages and small towns biomass castoff, municipal refuse biogas.Along with the raising of China's economic development living standards of the people, the development of industry, agricultural, aquaculture, a large amount of discarded object fermentation methane engineerings will be the effective methods that China's renewable energy utilization and ring protect.Because of the generation unstability of biogas, there is a lot of biogas to be confined to only supply with the utilization of life cooking or directly burn again, can not fully play its value.The utility model utilizes a kind of method simple to operation that biogas is used together with coal, and the biogas hot-air stove can be widely used in heating, and heating, in all trades and professions such as oven dry.
Summary of the invention
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of biogas and coal two to burn hot-blast stove.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of biogas and coal two burn hot-blast stove, comprise body of heater, it is characterized in that: described body of heater is provided with burner and heat-exchanger rig, described burner comprises burner hearth, burner hearth is provided with biogas combustion machine access port and the coal-fired mouth that adds, burner hearth bottom is provided with fire grate, and the fire grate below is provided with coal-fired slag notch; Described burner comprises some layers of heat exchanger tube, between each layer of heat exchanger tube, is provided with dividing plate, and bottom heat exchanger tube sidepiece is provided with the cold wind import, and top layer heat exchanger tube sidepiece is provided with hot-blast outlet; Described inboard wall of furnace body is provided with refractory masses, and the body of heater top is provided with chimney.
Described burner hearth bottom sidewall is provided with combustion-supporting air blast access port.
Described body of heater outside is provided with heat-insulation layer.
The utility model advantage compared with prior art is: 1, the heat exchanger tube of sandwich construction, and make the heat of biogas combustion long-time, the large-area furnace wall that touches, the time of director's exchange heat, thus greatly improve the efficiency of biogas utilization.Reduce the temperature of fume emission simultaneously.2, the accessible biogas combustion of this combustion chamber of furnace body, also can add coal as fuel, solves the undersupply problem of China's biogas because of climate temperature or other reason.
