(Eco-Eco) Biomass (straw) gasification furnace heating to new technology 
 This energy-saving products in the original boiler, furnace use reconstruction 
 In the transformation of the original furnace (Eco straw gasification furnace heating to new technology) investments in energy saving per year on renovation costs in full recovery! ! At present, China's air pollution is quite serious. As the fuel structure, coal accounted for the highest proportion, so China's air pollution is a typical coal-burning pollution, total suspended particulates, sulfur dioxide, nitrogen oxides are major pollutants. 
 Previously focused on air pollution in cities, but with the development of township enterprises, the regional air pollution to the spread of suburbs and rural areas, many rural enterprises to build chemical, textile, chemical fiber, leather, ceramics, glass, refractories, metallurgy so heat can be industries that use a large number of small boilers, furnaces, there is a low thermal efficiency, smoke and dust concentration degree black high temperature for a long time and other issues, a serious waste of energy, pollute the environment, the atmosphere has increased our pollution. 
 In order to improve the living environment and quality of the State Environmental Protection Administration of the country began to straighten out small boilers and furnaces to provide a small tonnage of a total ban on coal-fired boilers and furnaces, switching to natural gas, liquefied petroleum gas, diesel, heavy oil, coal gas , energy and other clean energy, transformation can not be scheduled to automatically shut down. In these clean energy, natural gas, liquefied petroleum gas and electricity supply difficulties exist, the shortcomings of higher cost, and coal gas is relatively cheap, so around the boiler, furnace coal gas-based transformation, various forms of gas furnace came into being. 
 Gas furnace with coal as raw material, air and steam as gasification agent, the production of low calorific value directly through the hot gas into the boiler or furnace combustion with high thermal efficiency, smoke emission characteristics of arrival. But with coal prices increase, coal-gas costs continue to increase, resulting in production costs also rising, affecting the economic efficiency of enterprises. 
 On the other hand, in China's vast rural areas, but continue to produce the crop residues and other biomass sources. China is a large agricultural country, produces at least a few million tons of agricultural and forestry waste, straw, because the original energy conversion means is low, rich farmers do not want to use time-consuming straw energy, resulting in rural biomass declining use of straw Every year a large number of biomass resources to be disposed of as waste, not only a waste of resources, but also causing serious environmental pollution and ecological damage. 
 Straw straw gasification is to improve the energy efficiency of an economically viable new technology, its principles and gasification of coal as raw material gas furnace is the same principle, but also to the air as gasification agent, through the furnace oxidation - reduction reaction, the straw into carbon monoxide, hydrogen and other combustible gas composition of low calorific value gas. The use of straw gasification, high efficiency, low pollution and so on. Through the straw into the furnace to heat the gas, its effect is the same as burning coal and gas. 
 In order to save coal resources, reduce pollution, the use of rural rich straw resources, production of straw to straw as raw material gas to replace coal gas, pass into the combustion boiler or furnace can supply clean energy to solve the problem of township enterprises, rural enterprises and because Most construction in the fields next to the straw is very easy to collect, reduce the cost of collecting the stalks, straw gas costs more to greatly reduce the cost of coal-gas, can significantly increase economic efficiency. 
 According to the tunnel kiln or kilns for small and medium scale manufacturing various specifications of straw circulating fluidized bed gasifier to produce gas directly into the furnace through the burner increases, providing energy to replace coal, energy conservation, reduce air pollution to improve the economic efficiency of furnace operation. 
 In a vertical furnace, for example, the furnace production of various types of light and heavy refractories, kiln production: 10 tons / kiln, each kiln heating time: 50 hours, the production cycle: open the kiln once / 10 days, the original type of energy: heavy oil, energy consumption: 4 tons of heavy oil / kiln. 
 If the straw into fuel gas furnace, the furnace just before the installation of a 1.2MW circulating fluidized bed gasifier, matched with a gas burner, you can completely replace the heavy oil, to achieve security, environmental operation, the fuel composition is 100% straw, the main process shown below. 


 Biomass gasification of biomass can be used to: corn stalks, corn cobs, cotton stalks, rice straw, rice husk, straw, husk, millet stalks, wood chips, bagasse, palm shell-based variety of crops, etc. straw, moisture content is generally 15 to 20%. Circulating fluidized bed gasifier with a wide adaptability of raw materials, rice straw, wheat straw, corn stalks and wood shavings, sawdust, bark and other agricultural and forestry waste can be used, according to the actual situation in rural areas around the kilns to collect a variety of raw materials to ensure the kiln operation.
