Using Biomass fuel for Process horizontal Steam Boilers Technical Report shows if the moisture content is too low for a given boiler design, combustion temperatures will increase and potentially cause problems with both flue emissions and ash-melting behaviour. Wood ash typically melts only above 1300 C, but other herbaceous fuels have ash-melting temperatures of ~ 1100 C. At excessive combustion temperatures, ash particles will condense on boiler tubes, heat exchangers and other boiler components and lead to corrosion or other irreparable damage to boiler parts.
"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired hot sale biomass burner for boiler usas eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.
Financial awards complement the way:
1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;
2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;
3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.
Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
Wood fired steam hot sale biomass burner for boiler usa in Thailand is widely applied in industrial fields because of its eco-friendly and economical. Thailand is an emerging economy and is considered a newly industrialised country. And its warmly developing industries need large scale machines such as industrial steam boilers. Biomass fuel is a kind of renewable resource, and Thailand has rich bioful resource. So, in Thailand, biomass fired steam boiler like wood fired steam boiler, rice husk fired steam boiler, palm shell fired steam boiler, etc is welcomed.
With the implementation of the new environmental protection law and the introduction of new standards for the control of atmospheric pollution of boilers, the transformation of coal-fired boilers in various localities has been carried out in an orderly manner, and coal-fired boilers can be transformed into natural gas boilers in the actual operation. Can also be transformed into biomass boilers, but no matter how to reform, in addition to the choice of high-quality coal-fired boiler transformation company, but also need to pay special attention to the following matters.
1. When the boiler is dismantled, attention should be paid to shutting down the blower and stopping operation when the boiler is dismantled, and when the furnace temperature drops to an appropriate temperature, the boiler needs to be dismantled by the relevant parts of the existing boiler to be retrofitted to the coal-fired boiler. Stop the boiler induced fan, chain grate, then the workers enter the furnace from the fire door, remove the original furnace arch of the boiler, clean up the furnace interior, and then remove the main engine and auxiliary machinery of the boiler.
2. Attention to furnace reform is one of the key points in coal-fired boiler reform. The combustion conditions of existing boilers can be improved by reasonable transformation, which can not only accord with the combustion conditions of new fuels, but also play a better role in saving energy. However, it involves re-pouring the furnace, so special attention should be paid to keep the back arch pipe of the boiler away from the center of the flame, so that it will not be burned by the high temperature.
3. Attention should be paid to the modified boiler after a series of projects, such as retrofit of coal-fired boiler, pouring of new boiler front arch and back arch, etc., should be paid attention to after the retrofit of coal-fired boiler is carried out. One of the most important tests is to test the boiler body under certain pressure, and the boiler can be put into use only after the boiler has passed the test and revamped. These are a few things to pay attention to when reforming coal-fired boilers.
