coal fuel fired steam boiler

CFB boiler can be divided into coal fired boiler and biomass fired boiler according the cumbustion fuel.ZG can design and supply CFB coal fuel fired steam boiler,CFB hot water boiler and CFB power plant boiler.The capacity of CFB steam boiler is 10-280ton,CFB hot water boiler is 20-160ton,CFB power plant boiler is 10-50MW.All these three types boiler play a vital role in industry.

Henan run several areas, including Henan gas boiler gas boiler operation includes several aspects: daily monitoring and adjustment operations; accident treatment; start and stop; optimal operation mode and technology improvements. When the normal operation of the boiler, the daily operation of the monitoring and adjustment of the operating accounts for the major part. "Stable" is the key, pressure, temperature, water level, negative pressure, milling parameters, etc., remain stable conditions is an important guarantee for safe and economic operation. Briefly, the steady working primarily by "balancing" the means to obtain, for example, outside the furnace combustion conditions and load balance, the pressure is stable; to balance the amount of water and evaporation, is stable water level; primer with the supply air volume the amount of negative pressure equilibrium is stable, according to Henan gas boiler operation adjustment purposes, and in accordance with the purpose of regulating the boiler operation, to take the necessary means of regulation. Daily adjustment of the key - "steam pressure." Among the major parameters of Henan gas boiler, main steam pressure to maintain stability is the key which only the steam pressure is stable, the remaining parameters to stabilize. Unstable steam pressure, steam temperature, the water level will also change, so first of all start from the pressure adjustment. Vapor pressure is divided into an outer and an inner interference disturbance, our plant, i.e. outside the external disturbance load generally little change, so change in vapor pressure are changed within the furnace i.e. interference caused by operating conditions, so holding furnace combustion conditions the stability is the stability of the vapor pressure. If the combustion conditions change, such as wind than powder, coal calorific value and other factors change, a pressure change occurs, requires us to be adjusted, thereby changing into a stable state of the combustion furnace transient state conditions.

Small electric coal fuel fired steam boilers What are the benefits, features? First, electric and coal, oil steam generating comparative advantages and disadvantages: advantages and disadvantages of coal: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce about 6 kg steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of coal-fired boilers and human factors affected the Boilermakers, the real heat of the steam is converted to produce much smaller than the theoretical value, the heat utilization rate of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, to ban small coal-fired boilers is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than coal.

Recently, the Jiangsu provincial government issued "Jiangsu Provincial Environmental infrastructure building program for three years (2018-2020 years) notice", the "notice" clearly states that, by 2020, the province's natural gas power generation installed capacity reached 20 million kilowatts, total coal consumption reduce 32 million tons more than in 2016, non-fossil fuels in primary energy consumption to 11%. Encourage waste incineration plants, cement plants, coal-fired power plants, organic fertilizer plant and other social resources co-sludge treatment and disposal, and given tariff or price subsidies.

Before the end of 2019, according to planning requirements cogeneration, coal-fired boilers and small coal-fired thermoelectric backward within the range of 15 kilometers radius of more than 300,000 kilowatts of heating cogeneration power plants all closed down integration, encourage the integration of southern Jiangsu shut down 300,000 a small thermoelectric fired boilers and heating within 30 km radius kW and above cogeneration plant. Distributed as the focus, ordered Qin decentralized wind power, distributed photovoltaic development, accelerate the distributed energy market transactions, and can complement other types of multi-national and provincial pilot.
