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.
CFB technology burns fuels without fire or burners in the furnace but through a process of fluidization mixes the fuel particles with limestone which captures the sulfur oxides that are formed and the low temperature reduces nitrogen oxide formation. The limestone and fuel are recycles multiples times which increases both the efficiency of producing high quality steam to produce power and also reduces pollution due to its ability to burn fuel in a clean way than the conventional processes. Circulating fluidized bed technology(CFB) also offers the flexibility of using both coal as well as biomass fuels.
In early 2019, Hebei Province Department of Finance summarized the draft 2018 budget and financial performance in 2019 budget, which states that: 2019 in terms of air pollution control to invest 8.23 billion yuan, the focus for rural clean heating, open pit mine remediation, new energy vehicle application, shutting down out of thermal power and other aspects. Specific details are as follows.
First, support for air pollution control
Continue to increase investment, air pollution control for the central funds 6.372 billion yuan, accounting for 31.9% of the total size of the national capital, the total ranks first in the country; the provincial capital issued 8.93 billion yuan, an increase of 6.78 billion yuan over the previous year, investment as the largest ever. Strong support "double generation" implementation of the project, the timely disbursement of rural "double generation" subsidies 6.627 billion yuan to protect people's warm winter; newly acquired Handan, Xingtai, Cangzhou, Zhangjiakou City 4 become a pilot clean warm winter, the province currently 8 atmosphere contamination of the transmission channel and the city of Zhangjiakou city have all been incorporated into the national pilot for three years will receive a total of 14.1 billion yuan of central funds.
Combustion effect is important to each industrial biomass 208 ton boiler agents. Wood fired steam boilers is a kind of biomass fired boiler manufactured in our ZG company. Wood biomass fired steam boiler can be designed into chain grate steam boiler (stoker boiler) or CFB steam boiler with consumer’s requirement. Industrial stoker boilers and fluidized bed boilers have specific operating features with biomass fuels depending on the fuel characteristics and site requirements. Here, we suggest that according to engineers advice and industrial requirement to choose boiler type. In ZG Boiler, our advanced engineers are committed to enhance combustion effect of each industrial steam boiler.
