example 1

[0023] The biomass is cotton stalk. After the cotton stalk is pre-processed (less than 50mm in length) and dried (with moisture less than 12%), the biomass crusher invented by the inventor is used to prepare it into a biomass micron fuel, which is composed of 100% plants. In the mass fraction of the fiber powder, the particles smaller than 50 microns account for 30.5%, those smaller than 100 microns account for 71%, those smaller than 250 microns account for 96.5%, and those smaller than 400 microns account for 100%.

[0024] The biomass micron fuel is placed in the fuel hopper, and the biomass micron fuel is given by the quantitative feeding device, and is mixed with an appropriate amount of air to form a dust cloud. (300mm in diameter) under the ignition conditions of pre-ignited firewood and waste paper flames, the micron fuel is heated and gasified into combustible gases such as carbon monoxide, hydrogen and methane, and burns with air, and the furnace temperature continues...

[0030] The biomass is cotton stalks, after the cotton stalks are preprocessed (less than 50mm in length) and dried (moisture is less than 12%), the biomass crusher invented by the inventor is used to prepare biomass micron fuel, which is composed of plant fiber powder 75%, coal powder 20%, red mud powder 5% (<150 microns). The particle size of the plant fiber powder is less than 50 microns, 30.5%, less than 100 microns, 71%, less than 250 microns, 96.5%, and less than 400 microns, 100%.

Abstract

The invention discloses a high-temperature biomass micron fuel. The high-temperature biomass micron fuel comprises 75 to 100 mass percent of vegetable fiber powder and the balance of additive, wherein the additive is at least one of coal powder, lime powder and red mud; and more than 70 percent of the vegetable fiber powder has the grain diameter of less than 250 mu m. Because the specific surface area of the biomass micron fuel is large, the biomass micron fuel can finish solid-gas conversion instantly under the action of the high temperature of a hearth and is decomposed to be combustible gases such as hydrogen (H2), carbon monoxide, methane and the like; the combustible gases combust with oxygen rapidly and vigorously; the energy is released in an explosive model; a high-temperature effect is formed; and the combustion temperature can reach over 1,300 DEG C and the fuel efficiency is over 96 percent. Compared with the traditional method, the method using the high-temperature biomass micron fuel has the advantages that the combustion temperature is increased by about one time and the combustion efficiency is increased by more than one time. The common biomass fiber material can perform fluidization transportation by a micron technique so as to form a high-grade fluid fuel near the grade of fuel oil and fuel gas. The high-temperature biomass micron fuel can be widely applied to thermal power generation, metal melting, the desalination of sea water, urban heating, lime burning, heating air conditioners, industrial heating and the like.

Description

technical field [0001] The invention relates to a renewable clean energy technology, in particular to a high-temperature biomass micron fuel. Background technique [0002] With the increasing depletion of petrochemical energy and the gradual exposure of the environmental harm caused by combustion, biomass energy has increasingly attracted worldwide attention due to its renewability and cleanliness. According to the statistics of the Swedish National Energy Agency, due to the use of biomass energy, the percentage of fossil energy in total energy consumption decreased from 80% in 1970 to 33% in 1998, while biomass energy increased from 9% to 15%. %, and the use of bioenergy is still growing rapidly. The development of biomass energy can not only make rational use of agricultural and forestry wastes (such as straw, branches, leaves, waste furniture, etc.), prevent energy waste, increase economic benefits, but also reduce CO 2 , SO 2 , NO X and soot and other emissions, alle...
