coal fired boiler d type

CFB coal fired boiler d type as a new technology also can be called clean coal technology,fully take the advantages of flexible burning fuel.ZG boiler company is a CFB boiler manufacturer with 70 years history,have unique advantages in this technology.CFB boiler can burn various type coal and biomass.Most industries mixing coal and biomass as fuel for CFB boiler during industry processing in Germany.

Coal dust fire type biomass power plant coal fired boiler d type type

In the power generation industry, the most common biomass combustion technologies fall into three categories: stoker/grate firing, fluidized bed combustion (FBC)—including circulating fluidized bed (CFB) and bubbling fluidized bed (BFB) boilers—and suspension firing or pulverized fuel (PF) firing.

Today I saw that when the capacity is the same, the furnace of the oil-fired coal fired boiler d type is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.

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.
