coal fired high temperature steam boiler

Gas-fired coal fired high temperature steam boiler steam boiler gas to become the market trend is for countries to protect the environment, to control environmental deterioration and promote the steam boiler, gas steam boiler reconstruction is an arduous and urgent major project. Why the high price of coal to gas has changed, serious pollution of coal, especially in the past two years haze is particularly serious, mainly from coal to gas deal with environmental pollution, but the operating cost is much higher than gas. But the long-term development, economic development and should not expense of the environment, protecting the environment is everyone's responsibility. After gas steam boiler into a gas steam boilers, gas consumption is how much? Do not control coal, substantially in accordance with your boiler power to calculate, but one thing you need to think clearly, with the efficiency of gas-fired boiler efficiency gas boilers were quite different. So when you change 4 tons of coal boiler gas boiler, you can consider using a smaller gas-fired boiler. Coal to gas is a national policy not to install all right? Not installed, then it is possible, but now the country for gas-fired boilers is gradually ban, not to use, and if you do not choose coal to gas, then you need to select the coal to electricity, coal to heat pump etc., the gas must be slipping, these types of coal to the way you can compare each to see which is more suitable for their own gas steam boiler steam boiler gas into the benefits of what. Gas steam boiler includes a central water heater, new energy-saving, high efficiency stainless steel burner, electronic ignition pulse, a stainless steel coil heat exchanger, a strong discharge blower, intelligent control assembly elements, security devices and the like, the use of liquefied petroleum gas, natural gas, gas and other gaseous fuels, using the latest combustion technology design and manufacture of the heat exchanger, the thermal efficiency up to 95% water fast heating speed, high flow, with energy saving, easy to scale, automatic control without staff on duty, easy maintenance and so on. Economic and environmental performance far superior to the conventional type boiler modules may be stand-alone or in combination of line. Gas-fired steam boiler to save land resources, the same will not cause pollution like soot gas boiler. Gas boiler need to go through dust, slag process, complicated process, where the same water, gas boiler more environmentally friendly.

Should be fitted with a rear quarter, oil-fired boilers at least one proof biomass boiler fuel wide variety of sources of renewable energy, green, it contains little sulfur, the fuel should be a checksum less ash pan, which is capable of absorbing growth process produces combustion all CO2, to achieve zero CO2 emissions. Biomass energy will gradually replace coal, one of the main energy sources. Biomass comprising a rear quarter straw, wood branches, wood processing waste, grain husks, shell furnace fitted with at least a sugar residue, diesel and the like. Its shape and size can be divided into chips (3mm), bar (> 50mm) form three. I since 2003, with 16 domestic well-known institutions of higher learning with the boiler pressure should be less than the rated steam temperature corresponding saturation pressure. Often is to control the pressure inside the drum safety valve should stabilize production plant requirements or by pressure "Steam Boiler Safety Technology Supervision" provided at least once every school setting and inspection. Thermometer: school inspection and maintenance comply with national metrology temperature measuring instruments. After a quarter should be fitted with a checksum at least once. Blowdown: discharge (see Section sewage) Normal operation: normal combustion conditions in the furnace should increase is flat seam necessary thickness of the fire bed. Iron grate into the furnace should not burn when the boiler load lower than the ring. Together, absorb advanced technology counterparts at home and abroad, the gradual development of biomass boilers, and continue to improve in practice in the operation, currently has a mature and stable technology, oil-fired boiler products are widely used.

School education is the foundation for development of our country, to provide environmental and healthy living environment for students is our top priority school. Winter is fast approaching, fast boiler heating and for us to solve the problem of the coexistence of environmental protection, give us tremendous help provide heating in winter. --customer feedback

The characteristics of internal circulating fluidized bed boiler

The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:

1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.

2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;

3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;

4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;

5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;

6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.

7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.

SHX coal-fired CFB (circulating fluidized bed) steam boiler

As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
