Straw vaporizer furnace project itself is problematic, straw gasification of this technology is indeed there, and has been out for a long time, as if in almost 8, 9 years ago I heard. However, from the practicality, operability and cost considerations, currently only used in power plants and straw vaporization station Use, such as Faku County, Liaoning Province, the establishment of a power plant, other regions also have a lot of intensive straw gasification station set up, but basically not a few years are shut down. The principle of straw vaporization is that the biomass (including straw, according to wood, firewood, weeds, pine needles and leaves, crop residues, dried cattle and sheep animal manure, edible fungi residues) in the absence of oxygen at high temperatures, resulting in a thermochemical reaction of the energy conversion process, the plant in the quality of the atoms of the elements of carbon, hydrogen, oxygen, etc., under the conditions of the reaction in accordance with the principle of bonding of chemical bonding, the generation of carbon monoxide, methane, hydrogen, and so on, combustible gases. Thermochemical reactions are generally divided into the following four steps, drying, thermal decomposition (also called dry distillation), reduction, oxidation. Among them, the drying layer requires a temperature of 100-250 degrees Celsius, the thermal decomposition layer requires 300-800 degrees Celsius, the reduction layer requires about 900 degrees Celsius, the oxidizing layer is about 1200 degrees Celsius, the principle is relatively simple, but in order to achieve the purpose of gasification as well as from the boiler design point of view, need to meet a lot of requirements, the gasification process of straw gasification is generally up-sucking and under the suction of two types Simply put, the upper suction type, that is, the raw material from the upper inlet input, after drying, thermal decomposition (also known as dry distillation), reduction, oxidation, four steps, and at the bottom of the fan forced air, in the upper part of the gasification generator Output gas, the lower suction type is from the upper inlet input, after drying, thermal decomposition (also known as dry distillation), reduction, oxidation, four steps, in the gasification generator with the induced draft fan in the lower part of the gas forced input gas, because the lower suction type fixed bed gasification process is relatively simple, but to gasification purposes and from the boiler design considerations need to meet many requirements. The downward suction fixed-bed gasification process can crack the tar twice, which can effectively reduce the tar content in the product. Therefore, the currently applied process is mainly based on the downsuction fixed-bed generator. The overall process flow of standard straw vaporization is like this: firstly, straw and other raw materials need to be washed and desulphurized (or other desulphurization methods), and then naturally dried in the sun or automatically dried, and then crushed into the length of 3mm-30mm with a crusher (crushing of the raw materials has a small effect on the tar content, and mainly affects the efficiency of the gasification), and then put into the "gasification generator", and then after drying, crushed into the length of 3mm-30mm with a grinder. "After drying, thermal decomposition (also called dry distillation), reduction, oxidation of four-step reaction, the generation of combustible gases, and then through the dust collector dust, and then through the spray purifier, vapor separator, filters, and finally into the storage tanks, is qualified, can be used for combustible gases. Then it will be delivered to the people's homes to burn and use. Please be careful! I have not been using the term "gasifier", in fact, in the biomass gasification system has a "gasifier" this equipment, but the "gasifier" standard should be called "gasification generator", which is only involved in the thermochemical reaction of biomass (i.e., drying, pyrolysis, reduction, oxidation of the four steps), rather than with the nature of combustion of our common people's lives in the ordinary "stove", and If A product advertised gasifier even And if a product advertises that the gasifier does not even need to crush the raw material is just chopped, 100% is a liar, that is not a gasifier at all, it is simply an ordinary coal-burning, wood-burning "stove". In the factory gasification generator, the highest biomass gasification efficiency is only up to (87.2%), generally is about 70%, and the publicity of the "gasifier" such a small volume, the temperature and time of the thermal reaction is very limited, the gasification rate is very low, the gas production is insufficient, the fuel is not pre-desulphurization, producing more tar, the "gasifier", "gasifier", "gasifier", "gasifier", "gasifier", "gasifier", "gasifier", "gasifier", "gasifier". "The temperature and time of thermal reaction are very limited in such a small volume, the gasification rate is very low, the gas production is insufficient, the fuel is not desulphurized beforehand, and it produces much tar, which is very corrosive to the "gasifier" as well as to the pipeline. Straw vaporization of thermochemical reaction of the temperature and time control requirements are relatively more stringent, the temperature and time to reach, either can not be gasified, or gasification is not sufficient, gas production is insufficient, the remaining residue of straw on the more, not like the TV, the network propaganda, as long as the firewood and grass chopped up, put it in, covered with a lid, light the fire on it, it is irresponsible, with deceptive propaganda, to put it bluntly, is a blind man. That is irresponsible and deceptive propaganda, to put it bluntly. Biomass gasification process equipment requirements are high, the investment is large, usually millions of dollars, is only suitable for investment in straw vaporization stations and power plants to use, in terms of its miniaturization. It is not practical, economical or realistic. I looked on the Internet, there is even "infrared gasifier"! Really blowing no edge! At present, the market "gasifier" are not qualified, and can not be said to be the real "gasifier", the real "gasifier" no miniaturization, are complete sets of equipment. As a person engaged in boiler design, I strongly do not recommend everyone to do this business, not to be cheated on God's sake ！！！！ A lot of online chain business does not have the operability, I hope that we should be calm, rational analysis, do not know how to ask the industry, do not be impulsive ah,
