First, to improve the fuel will be coal into gas in principle, more in line with the relevant environmental standards, coal as fuel for the coal boiler large 2 5million btu coal boiler has been subject to the authorities to stop, that there is often a company will be coal-fired boilers on the boiler rehabilitation programs into gas boiler embodiment, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second, improve coal-fired furnace boiler furnace to transform into a blast furnace gas fired boiler is the use of auxiliary heating furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion furnace gas gathering or tail, it is very prone to catch fire or explode, then the need for means to improve the furnace blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third, improve the pre-attached devices did not improve during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate and so on, after adoption of these boiler ancillary equipment gas furnaces do not need to use so that you can save and invest more of boiler equipment. Fourth, improve environmental protection degree We all know that coal-fired furnace has been impermissible environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, after making use of the boiler gas furnace, greatly reducing soot and various soot emissions can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with the standards of environment protection and energy policy.

In response to national environmental policy development, improve the quality of people's living environment of the area, Guangdong Province, actively promote the coal boiler large 2 5million btu coal boiler "coal to gas" action. Currently, Dongguan City, "from coal to gas," the work has entered a crucial stage, nearly two months, the city government, city atmosphere Office, the Municipal Development and Reform Bureau has organized a thorough inspection teams to supervise the Towns "coal to gas" work . Atmospheric do inspection personnel Lurui Quan admits: "From the inspection situation, many companies on the 'coal to gas' is still in the wait and see attitude, worried about the safety and cost issues."

As of March 25, Dongguan City, 26 companies of 37 coal-fired boilers (except coal-fired captive power plant boilers), it has been out of the 17 units, 14 companies were using natural gas. In addition, 12 companies of 20 coal-fired boilers, is expected to complete phase transformation within this year.

It is expected that in the near future, all industrial boilers transform the use of clean energy, Dongguan sky will be bluer.

Chemical plant coal boiler large 2 5million btu coal boiler combustion efficiency improvement measures which are not high chemical plant boiler combustion efficiency is not high improvement measures what? The low-temperature exhaust gas boiler combustion efficiency test, a higher excess air ratio, suggestions for improvement higher problems: 1, the excess air ratio due to lower general, industrial boilers was 1.4. Due to the different internal structure of each of the boilers, excess air coefficient can be adjusted according to the actual operation, there are sufficient coke burn time in the boiler. Additionally, secondary air may be suitably provided, coke sufficient oxygen for complete combustion, reducing the incomplete loss of solids. 2, due to lower exhaust gas temperature of the boiler exhaust gas temperature account for a large proportion of the boiler heat loss, so the loss of the boiler must be minimized. In one aspect, the dew point should be to prevent corrosion; the other hand, the exhaust gas temperature is not so high. 3, to improve the uniform distribution of air to the boiler furnace combustion efficiency, so as not to cause incomplete combustion of the coal formation dead. As the pilot were grate boiler, the moving speed of the chain should be controlled within a reasonable range of coal on the grate have enough time to complete combustion, but not too long so as not to waste grate. In addition, high-volatile coal, the coal should be possible to improve the quality, to shorten the combustion time, reduce the loss of solids of incomplete combustion.

Lignite Power Plant CFB Boiler in Turkey

The size of CFB’s designed for lignite coal as primary fuel can vary in a broad range of steam capacity,from industrial to large-scale utility boilers.Additionally, many of the CFB power plant boilers designed for coal feature the well-known fuel flexibility capability adding fuels such as biomass and various types of waste which are co-fired simultaneously.
