1t gas hot water boiler Seller Bhutan

Coal-fired steam boiler scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.

Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.

25MW CFB boiler used for co-generation has the advantages of water saving, power saving, no clean gas reheating necessary, no need for special materials for corrosion protection and so on, it has excellent technology-economy, especially in flue gas desulfurization projects of large-scale and low-sulphur coal fired power plant units or at water deficient areas.

It provides fast side of boiler equipment, installation and commissioning after all normal, we immediately put into use, the hotel did not delay the normal heating. Meanwhile boiler capacity, energy efficient, fully able to meet the needs of heating and bathing water in our hotel rooms. --customer feedback

The cost of generation depends on quality of coal because of high ash content in coal will have impact on boiler efficiency, the tube leakages will occur frequently that will increase maintenance cost and increasing trend of forced unit outages. Washing of coal reduce the ash content, but expenditure on this account increases cost of supply.
