small coal fired boiler in power plant

When coal-fired small coal fired boiler in power plants, coal-fired boilers need to use technological innovation to promote energy conservation and environmental protection is an important step in the process of our country, many cities are very encouraged coal-fired boiler reconstruction project, giving premium policy, depending on the duration and scale of reform. So when coal-fired boiler, which are more commonly used technology? Following on from the transformation of high-quality brand of coal-fired boilers - fast boiler party, to present to you. 1, coal-fired boiler auxiliary blowers and energy-saving technologies induced draft fan energy consumption and thermal efficiency of coal-fired boiler operation parameters directly related, appropriate conversion technology can be used for coal-fired boiler, the boiler load in accordance with the transformation requires adjusting drum, the air volume to maintain optimum conditions of operation of the boiler, the boiler can save not only coal, but also reduce the power consumption of the fan, so that to achieve a better energy-saving effect. 2, the transformation of coal fired boiler technology devices are currently grate-fired boilers burning coal, which accounts for the majority of coal-fired boilers in the coal boiler will hinder into the wind, affecting the combustion. When the coal-fired boiler coal bucket coal transformation component layer, using gravity filters to block coal, coal bottom-end loosely distributed on the grate, the air inlet beneficial, to improve combustion, improve coal combustion rate, reduce ash carbon content. 3, combustion coal-fired boilers by the transformation technique of this technique coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of suspension firing increases, must be obtained the saving rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed. These are more commonly used in coal-fired boilers to several techniques, since each technique is suitable for different types of coal-fired boilers, so companies want to transform the existing boiler, then they would have to consult the excellent quality of the coal-fired boiler company and then consider and select an energy-saving effect is most obvious, to maximize the advantages of technological transformation of coal-fired boilers.

Fangkuai Group insists on using sophisticated equipment and technology to ensure operation accuracy, increase rigidity and surface finish, reduce wear, ensure excellent performance, and ensure stable and reliable manufacturing quality. It has a domestic Class A small coal fired boiler in power plant manufacturing license issued by the General Administration of Quality Supervision, Inspection and Quarantine. It has been based on quality for many years and has obtained a number of authoritative quality certifications.

Major effects of fuel on small coal fired boiler in power plant design

1.A wide range of coal properties can lead to over-sized pulverizing/firingequipmentwhich will in turn lead to a limitation on turn down and a possible increase in auxiliarypower consumption. This will also increase the furnace size and the SH and RH will need to be sized properly, which can be difficult at times, to get the rated outlet temperature.

2.Over-sizing of pulverize-rs and air heaters to handle occasionally high moisture coals will require excessive tempering air when handling normal moisture coals. Ultimately all these will result in higher gas outlet temperature, reducing the horizontal boiler efficiency.

3.The behavior of the ash during the combustion process and managing the coal-ash are the major issues in horizontal industrial boiler design. Deposition and slagging, heat transfer upsets, and fouling in convection passages are some of the major issues to be dealt during operation of the boiler.

The difference between Henan coal-fired small coal fired boiler in power plants and gas boilers no matter what gas or coal can be used as fuel for boilers, however, named according to different types of boiler fuel use are not the same, so there is a gas boiler Henan and gas boiler that different types of boilers. So both types of boilers in addition to the fuel used in the combustion is not the same, between Henan coal-fired boilers and gas boilers, what difference does it make? 1, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while Henan gas boiler start and stop very convenient, fast warming intermittent operation, thereby reducing heat loss in this process. 2, after the treatment of different coal-fired combustion in the boiler will produce large amounts of ash after combustion, in order to maintain a good healthy environment need to transport ash to the professional field slag processing, however, gas-fired boiler using gas , there will be no remaining after combustion ash, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies. 3, the fuel is coal flue gas of coal-fired boilers used in different, when coal combustion will have a greater smoke caused serious pollution to the environment, however, high stability of the gas after combustion boiler did not smoke exhaust, because the basic gas on can be completely burned, toxic black smoke can reach zero ringelman level, SO2 content of which is very small, so there is no pollution to the environment. These three points above are some of the differences between Henan coal-fired boilers and gas boilers. By introducing the above we can understand the essential difference between the two boilers can understand, Henan gas boiler it is because of more environmentally friendly energy was gradually replace coal-fired boilers.
