Industrial efficient brown coal hot water dzl boiler energy saving measures which are currently the main problems of industrial boilers have low thermal efficiency of boilers, energy can not be effectively utilized, resulting in waste; old boilers, automatic control level is not high, affecting boiler combustion efficiency; energy-saving regulation in place, and many other issues . In order to prevent pollution of the environment, reduce energy consumption, industrial boiler energy saving technical measures as follows: (1) the transformation of coal to the device. The modified ingredients bucket coal to the coal layer, using gravity filtering, the pulverulent raw coal, lump coal from top to bottom on the grate loosely distributed, facilitates air intake, improve combustion, improve the combustion rate of coal, reduced ash carbon content. (2) the transformation of the combustion system. For forward Stoker, the transformation from a combustion system is injected into the furnace in place an appropriate amount of pulverized coal to the furnace in place, so that the combustion grate base layer, the increase amount of suspension firing. (3) the transformation of furnace arch. According coal actually used, appropriately changing the shape and position of the furnace arch, can improve combustion, improve the combustion efficiency. (4) Transformation of grate-fired boiler circulating fluidized bed boiler. Employ a circulating fluidized bed boiler is a pulverized coal boiler in the furnace of the circulating fluidized combustion mode, which is 15-20% higher than the thermal efficiency of the boiler burning layer. For a variety of coal, limestone powder may be used in the furnace desulfurization, greatly reducing the content of the flue gas emissions of S02. Using (5) inverter technology, auxiliary boilers transformation. (6) The automatic control system, real-time adjustment of the heat output of the boiler, to save energy. (7) recovering the condensed water. (8) boiler replacement, replace old boiler with a new boiler. (9) flue gas discharge system reform.
The boundaries of the efficient brown coal hot water dzl boiler and large boilers and boiler combustion method usually used in home heating or bathing more, there is a small naturally large boilers, both of which boiler has a very clear difference, even the demarcation has many new the user does not make equipment for combustion, the following'll tell you about methods of water and fuel demarcation between the two: First, the demarcation of large and small boiler boiler boiler capacity according to the size of the boiler has a large, medium, small of points, but there is no fixed, definite boundaries between them. With the development of China's power industry, power plant boiler capacity is increasing, and the boundaries of the capacity of large and small boilers will continue to evolve, from the current situation, the generated power is equal to or greater than 300MW boiler unit configuration for large boilers. 1T is bounded by Second, the correct combustion method, the water fill, fill the tank to keep less than half tank of water. All the radiator bleed valve deflated until the water --- pay attention to add water. 2, the briquettes ignited on the gas stove, coal stove put in --- must take the good eye. 3, the pressure of coal, opening the damper. 4, Kai furnace few days to wash bleed radiators, Qin replenishment. In fact civilian life boiler boiler, its small size, low power consumption, a typical feature is suitable for home use. Two kinds of boiler From outward appearances it seems like, in order not to confuse, we have to remember their boundaries, to master the correct combustion methods help us to secure the future use.
Main steam efficient brown coal hot water dzl boiler 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.
School education is the foundation for development of our country, to provide environmental and healthy living environment for students is our top priority school. Winter is fast approaching, fast efficient brown coal hot water dzl boiler heating and for us to solve the problem of the coexistence of environmental protection, give us tremendous help provide heating in winter. --customer feedback
