Oilfield Boilerscustom Oilfield Steam Generator
China is the large number of small coal fired boilers, this part of the boiler unit is particularly suitable for the use of straw fuel fired , there are several reasons:
1.Biomass own characteristics, such as low density, to collect raw material, transport and storage has brought great difficulties, according to the level of tariffs in different regions, the general raw material transport over 50 km or more, its economic competitiveness will be substantially reduced, even though they have adopted the compression molding technique .
2.China's current majority of small coal-fired units desulfurization equipment is not installed, this part of the unit coal consumption is not only large, but also the level of SO2 and dust emissions are also much higher than the fire power units, even superior environmental performance of circulating fluidized bed boiler units, because of cost considerations, most of the circulating fluidized bed boiler unit of limestone system is not put into operation. Therefore, the use of existing small units burning low sulfur, low ash biomass fuels, substitution of coal, coal used for savings and efficient, the installation of desulphurization equipment fire power units, which alleviate pressure on the environment is very beneficial .
3.More importantly, the circulating fluidized bed boiler fuel for its wide adaptability, fuel for co-firing biomass basic need to make any changes, but also to bring the combustion efficiency, reduce emissions and slow down wear a wide range of benefits. This may make small generator / heating circulating fluidized bed boiler unit occupies an important position in the future utilization of biomass resources.
Relationship between generator capacity and boiler capacity
From the energy point of view, the power generation process of the power plant is essentially a process of energy conversion (chemical energy → thermal energy → kinetic energy → electrical energy).
Recently, the Fujian Provincial People's Government formulated and issued the "Fujian Blue Sky win the Battle of three-year action plan to implement the program" (the "Program"), "plan" will fully implement the spirit of the party of nineteen, in strict accordance with the National Ecological environmental protection requirements, adhere to the development of new concepts, rule by the people, respect the source of prevention, treating the symptoms and so on, determined to win the battle of the blue sky.
"Program" Total thirty-nine, according to Xiao Bian finishing, a total of six boilers relevant content for your reference.
1, deepen industrial pollution control. As of the end of 2020, the completion of the sewage pipe catalogs specified in the license issued by the licensing industry issues, increase exceeded, waste-water treatment, fraud and other illegal activities. Promote key industries pollution control upgrades, the focus control area will strictly implement the Ministry of Environmental Protection issued the "Notice on the implementation of air pollutant emission limits in particular", the use of natural gas, Fuzhou, Quanzhou, in principle, two new projects to further promote the building construction ceramics ceramics pollution remediation; Zhangzhou City, the implementation of boiler "coal to gas" project.
2, optimizing energy structure. Until 2020, primary energy consumption control in 142 million to 1.62 million tons of coal, coal in primary energy consumption is reduced to 41.2%, increase the proportion of clean energy to 28.3%.
3, accelerate natural gas applications. Speed up the construction of natural gas infrastructure, improve the natural gas pricing mechanism, to further increase the use of natural gas.
4, an alternative propulsion power. Transportation, construction, industry, food, agriculture, tourism and other fields to accelerate alternative energy work. By 2020 the proportion of energy use accounts for about 29%.
5, deepen the comprehensive improvement of coal-fired boilers. Eliminated, shutting down 300,000 kilowatts of coal-fired boilers environmental performance is not up to energy security. And to carry out comprehensive improvement of the way and central heating coal-fired boiler. Cities above county level out of 10 tons of steam / sales and less coal-fired boilers, no new 35 steam tons / hour of coal-fired boilers.
6, strengthen the construction and management of the combustion zone ban. Each urban renovation to increase the range of high-pollution fuel combustion zone ban according to a division range, and punishes violation of the ban on burning zone management requirements.
7, improve energy efficiency. Dual control sustained energy consumption and working examples intensity. Strict management of energy-saving, energy-saving equipment industry and other key areas of work, to promote energy-efficient technology and low nitrogen products.
8, expand industrial furnaces governance. Localities to develop according to their industrial furnace implementation of comprehensive improvement program for non-compliance of industrial furnaces, small and medium sized furnace gas generator out of efforts to encourage the use of electricity, natural gas and other clean energy.
All cities in Fujian Province will strictly follow the "program" the development requirements of the implementation of the measures, so that the people responsible life, contribute to environmental protection goals.
Vietnam Biomass CFB boiler in Sugarcan Mill Technology
The prime technology for sugar mill cogeneration is the conventional steam-Rankine cycle design for conversion of fuel into electricity.A combination of stored and fresh bagasse is usually fed to a specially designed furnace to generate steam in a boiler at typical pressures and temperatures of usually more than 40 bars and 440°C respectively.The high pressure steam is then expanded either in a back pressure or single extraction back pressure or single extraction condensing or double extraction cum condensing type turbo generator operating at similar inlet steam conditions.
