Cement Coal Boiler

2018ISH heating HVAC industry event, fast Boiler "Thalia T7" was set aside to hold the event May 23, ISHChina & CIHE China (Beijing) International heating ventilation air conditioning, heat pumps fresh air and home comfort systems and technology exhibition in Beijing International Exhibition hot center opening.

A cement coal boiler thermal efficiency improve conventional coal-fired boiler mostly thermal efficiency of about 70%, a large portion of the energy due to heat loss or otherwise be wasted, the use of gas boiler after the "coal to gas", the thermal efficiency will be 20% -40% improved. Second, lower investment costs than the price of coal gas prices high, but in addition to fuel costs, only the investment pipeline can. The investment in coal-fired boilers in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap. From the cost point of view, natural gas overall advantage. Third, improve environmental benefits due to the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise.

Chain Grate type cement coal boilers are likely the oldest commercial combustion technology still in use today. There are several types which have been enhanced through the years and are capable of firing biomass. But In fact, grate type boilers are among the most popular combustion technology for small to medium sized biomass-fired boilers.CFB boiler is a new clean coal technology which can co-firing coal dust and biomass for power plant,that need large capacity.

Personnel and to avoid faulty gas cement coal boiler gas boiler prone to some fault in the use of the process in order to avoid it fails, we have to understand some of the considerations when using. When using a gas boiler, we should always carry out its care and maintenance of local failure timely maintenance and replacement, make sure it is working properly. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, and should be cleaned. Low temperature liquid phase heat carrier outlet of the furnace, for lack of heat, and the exhaust gas temperature exceeds 300 ℃, the main problem is the fouling, soot blowing should be. As low exhaust gas temperature, the main issue is burning, mainly lack of the wind. Although the pressure furnace, the blast volume is not open, the furnace temperature is low, combustion insufficient strength. We should focus on rear seal machine check furnace slag, dust, etc. whether closing the ash outlet is good, with or without cold air leakage into large. Before and after the filter differential pressure increases, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. Grate stuck. The reason is often broken or grate grate fall loose pins; coal grate has stuck to metallic inclusions; arched grate; slag filter (Eagles iron) sink tip and the grate stuck. Processing method: reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. The iron eagle sink, both sides can pull the fire door pull hook n. Grate stop turning, it may be too loose chain, and sprocket meshing well, or badly worn sprocket, and chain-linked bad; the adjustment screws on both sides to re-adjust the tension grate, if still does not work, you need to exchange sprocket.
