Background

The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. The boiler is a water container heated on fire, a furnace is a place where fuel is combusted, and the boiler comprises a boiler and a furnace. The hot water or steam generated in the boiler can directly provide heat energy for industrial production and people life, and can also be converted into mechanical energy through a steam power device, or the mechanical energy is converted into electric energy through a generator. The boiler for supplying hot water is called a hot water boiler, is mainly used for life, and has a small amount of application in industrial production. The boiler for generating steam is called as a steam boiler, often called as a boiler for short, and is widely used for thermal power stations, ships, locomotives and industrial and mining enterprises. A boiler heated by using heat conduction oil is called a heat conduction oil boiler. The heat conducting oil, also called organic heat carrier or heat medium oil, has been used as an intermediate heat transfer medium in industrial heat exchange process for over fifty years, and is widely applied to the industrial fields needing high temperature, such as petroleum, chemical engineering, pharmacy, textile printing and dyeing, light industry, building materials, food, road asphalt heating, and the like. At present, when people are heating and bathing, a normal pressure hot water boiler is adopted, the boiler body of the boiler is of an integral structure and mainly comprises an integral boiler shell and a boiler liner arranged in the integral boiler shell, an upper layer of transverse water pipe, a middle layer of transverse water pipe and a lower layer of transverse water pipe are arranged in the boiler liner, and a chimney positioned above the boiler shell is communicated with the boiler liner through a cupola pipe. The circulating water in the boiler circulates from bottom to top through a water storage chamber formed between the boiler shell and the boiler liner and a transverse water pipe communicated with the water storage chamber, and has the advantages of small heating area, large water capacity, high coal consumption and slow temperature rise. The combustion flame in the combustion chamber directly radiates the furnace pipe, high-temperature flue gas flows upwards to heat the transverse water pipe and then directly enters the chimney through the cupola pipe to be discharged, the flue gas flow is short, the combustion is insufficient, a large part of heat is discharged along with the flue gas, the heat efficiency is low, the temperature of the discharged flue gas is high, and energy waste is caused. At the same time, such boilers are also inconvenient to maintain. Most of the existing various boiler products are integrated, and have the defects of low energy utilization rate and serious pollution.

With the continuous advance of the industrialization process in China, the industrial pollution is continuously aggravated, some backward boilers with high energy consumption, high energy consumption and low output are gradually eliminated, energy-saving and clean boilers gradually enter the visual field of people, at present, the fuels of the boilers are various, the main fuel of the boilers is the raw material and is not stabilized, therefore, the fuels of the boilers are various energy sources at present, a plurality of collective units such as factories and schools far away from cities still use the traditional coal as the fuel, enterprises, institutions and schools around the cities or the cities mainly use the clean energy source, and the boilers which use gas, use biomass fuel and use anthracite coal and other energy sources are available, in the traditional boilers, because the boilers which use coal as the main fuel are used, coal burning devices can bring continuous pollution, at present, the boilers of the energy-saving and clean biomass fuels are favored by the society, however, if energy-saving clean biomass fuel is used in the original coal boiler, the problems of low efficiency and insufficient heat exist, and therefore, a boiler specially used for energy-saving environment-friendly fuel is urgently needed to be matched with the energy-saving clean biomass fuel. Due to the limitation of electric power and natural gas supply and gas pipelines, coal-fired boilers in China cannot be completely changed into electric boilers or gas boilers, and biomass boilers are low in price and running cost, so that the biomass boilers are easy to accept and popularize by users, and the blank is filled. The biomass energy granular fuel is prepared by crushing, mixing, extruding, drying and other processes of all waste crops such as straws, rice straws, firewood materials, wood chips, peanut shells, melon seed shells, beet pulp, barks and the like, and finally preparing the granular fuel. The biomass energy particle material is widely distributed in China, the processing technology is advanced, the biomass energy particle material is famous for green coal, and the biomass energy particle material is clean energy. As a fuel of a boiler, the combustion time is long, the temperature of a combustion-strengthening hearth is high, the combustion-strengthening boiler is economical and practical, meanwhile, the environment is not polluted, zero emission of CO is realized, zero emission of SO is realized, the boiler belongs to renewable energy sources, can be recycled, and can replace wood, coal and natural gas. And the operating cost is only half of that of gas. A large amount of agricultural raw materials in China provide strong material guarantee for the popularization of biomass boilers. The straw burning problem of farmers can be solved, resources are fully utilized, and burned ash is a very good fertilizer, so that the straw burning machine achieves multiple purposes. The Hengyang is thought to be that the biomass boiler can reduce the emission of PM2.5, powerfully promotes the development of environmental protection business, and is an important part of new energy strategy in China. The biomass boiler is a kind of boiler, and a boiler using biomass energy as fuel is called a biomass boiler and is divided into a biomass steam boiler, a biomass hot water boiler, a biomass hot blast stove, a biomass heat-conducting oil furnace, a vertical biomass boiler, a horizontal biomass boiler and the like. The boiler uses a reciprocating grate, which is the most suitable combustion equipment for biomass fuel combustion. The boiler is in structural design, and is great compared with traditional boiler furnace space, and the abundant burning of a large amount of volatiles that precipitate in the twinkling of an eye when being favorable to biomass fuel burning. The boiler can be equipped with a fuel oil (gas) ignition burner, so that the ignition automation is realized. The feeding, burning, deslagging, water supply and ignition of the boiler can be automatically controlled, and the operation is very convenient. The boiler is provided with an automatic ash removal device, so that the accumulated ash on the heating surface of the boiler can be removed in time, and the efficient and stable operation of the boiler is ensured. The tail part of the boiler is provided with a coal economizer and an air preheater according to the requirement of a user. Compared with the traditional boiler, the boiler has higher efficiency and low exhaust gas temperature. The efficiency of the biomass boiler is generally over 80 percent, the boiler is large in size, the combustion is more sufficient, and the efficiency of the boiler is higher. The highest efficiency reaches 88.3 percent, which is 15 percent higher than the average efficiency level of a coal-fired boiler.

Present all kinds of half gasifiers of living beings, especially the half gasifiers of current market ubiquitous thermal efficiency is low, heat utilization is not abundant, exhaust residual smoke temperature is too high, and produce the flue gas after the burning, the flue gas is through the afterbody flue, discharge after removing dust through external dust collector at last, flue gas waste heat does not make full use of, the very big energy waste has been caused, simultaneously because the inside difficult clearance of current boiler, lead to cigarette ash to pile up too much, heating efficiency reduces, extravagant fuel, and these factors often are the main restriction factor that influences the heating effect. The invention discloses a comprehensive utilization energy-saving device of a biomass semi-gasification furnace, which is disclosed by the invention with the publication number of CN201599824U and the publication date of 2010 being 10.6.4, and comprises a combustion chamber, a main gasification chamber, an auxiliary gasification chamber, a furnace bridge, a secondary ventilating duct, a filling opening, a fire retaining ring, a fire enclosure, a flue, an upper water jacket, a lower water jacket, a radiator, a kang inlet flue, a flue change-over switch, a water outlet pipe, a sprayer and a steamer. After the meal is done, the heating radiators of other houses can be driven to play the role of a small boiler. Although the invention can realize the effect of cooking, heating and bathing simultaneously and improve the heat utilization rate of materials, the invention has the following defects: although the air supply amount is increased by increasing the volume of the gasification chamber, the combustion degree of the materials is improved, the combustion of the materials can only be continued until the cooking process is finished, once the cooking process is finished, the air supply is finished, the materials can not be continuously combusted, the energy of the materials is greatly wasted, the combustion degree of the materials is reduced, and the energy saving performance is poor; therefore, the problems that the skilled person needs to solve urgently are: the multifunctional biomass semi-gasification furnace can not only supply heat for a geothermal heating kang, but also be used as a cooking bench, can improve the utilization rate of boiler flue gas, and enables biomass fuel to be fully combusted and is energy-saving.
