100 th coal steam boiler in indonesia
Main 100 th coal steam boiler in indonesia temperature abnormal phenomenon of how to do 1, main steam temperature anomalies alarm. 2, the rapid variation of the main steam temperature, a secondary damper frequently significantly reducing water operation. 3, starting superheat outlet steam separator above or below normal. 4, if the steam with water, the unit will water shock occurs. 1 reason, the fuel and water supply imbalance, the separator outlet temperature abnormality. 2, coal combustion conditions change or affect, such as excessive load lift; and pulverizing mill administration system abnormality stop; means automatically increase or decrease the failure rate is too large amount of wind and the like. 3, the central flame furnace changes, such as the bottom seal damage, W and inadequate flame downstroke. 4, the control failure by warm water, warm water flow rate reduction is abnormally reduced or increased. 5, feedwater temperature mutation. 6, does not match the wind coal. 7, the secondary combustion heating surface. 8, furnace coking or fouling seriously. 9, heating surface leakage squib. 10, flue gas damper opening degree is not normal. 11, coal sudden change occurred. 12, the uniformity of the powder feeding substantial change occurs. 1 process, failure caused by unit coordinated coal - water ratio should be immediately released coordinate offset, in accordance with the current load demand, with reference to the start of the steam superheat separator, and adjusting the amount of fuel corresponding to the amount of water, with one, two main desuperheating water rapidly steam temperature control in a normal range; when the coal - water ratio should avoid imbalance after coal and water while adjusting; when coal - water ratio is adjusted to further adjust the load after a relatively stable; contact maintenance processing timely. 2, when the water supply system fault condition occurs a significant disturbance furnace should pay attention and automatically coordinated working conditions, so as not to manual intervention, when not working properly coordinated and automated, should be manually adjusted, stable water flow, referring to separation according to the water flow steam superheat, the adjusted amount of fuel, with a secondary spray water rapidly controlling the main steam temperature within the normal range; contact maintenance processing timely. 3, due to rapid changes in load caused by the load change rate should be adjusted; load change caused due to protective operation or the like caused by heat load to be quickly adjusted to maintain the boiler pressure of the main steam stability. 4, by warm water automatic dysregulation, should be appropriate Save warm tone is switched to the manual may be an intermediate point of the feedwater control system be corrected for temperature if necessary, or the feedwater to switch control to manual control, due to lower lifting and lowering the load speed to prevent steam temperature, promptly contact a service process. 5, the boiler furnace cause severe fouling and coking of the main steam temperature anomalies can be corrected by an appropriate degree of superheat outlet steam separator start, adjust, and in a timely manner and the furnace heating surface sootblowing. When the platen superheater sootblowing or superheater outlet temperature is still above normal and a secondary reducing water damper fully open, to check the furnace and the combustion air distribution system is normal, the checking process to reduce still overtemperature unit load. 6, flue gas damper adjusted to an appropriate opening degree. 7, if the bottom seal after losing back to normal immediately. 8, to strengthen the turbine expansion, differential expansion, axial displacement of the shaft vibration and bearing temperature monitoring, if abnormal, the process according to the corresponding regulations. 9, after the above measures, if invalid, should immediately drop the load process. 10, in front of the main steam temperature main steam 50 ℃ drastically reduced within 10 minutes, should an emergency stop.
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas 100 th coal steam boiler in indonesia for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
what is chain grate boiler
Grate firing has been the most commonly used firing method for combusting solid fuels in small and medium-sized furnaces since the beginning of the industrialization. Coal, waste and biomass fuels are usually burned in grate boiler. In the chain boiler, the coal is moved backward from the front of the grate, and the air from the bottom up to the furnace, and as the furnace is constantly moving backwards, the fire, combustion, burning and other stages occur in sequence. Traveling or chain grate stokers feed coal out onto a rotating metal belt that supports the fire. Solid fuel is fed from a hopper. Grate speed is automatically controlled to maintain desired steam pressure. Burning progresses as the belt moves from front to back of furnace. Combustion is essentially complete at the back end of belt, and ash is dumped off into an ash pit there.
Overview of 10 Ton Gas Fired Steam Boiler
10 ton gas fired steam boiler for sale in ZG Boiler is a “D” type double drums water tube boiler, and its furnace hearth is adopted with membrane water wall structure.
