chain grate coal fired steam boiler for paper

Main chain grate coal fired steam boiler for paper 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.

Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas chain grate coal fired steam boiler for paper (WNS10-1.25-Y.Q).

Auxiliary means configuration of the auxiliary boiler apparatus comprising a boiler fuel supply means, air blowing means, the wind means, water supply means, means ash, dust removal device, instrumentation, valves and other automatic control device. Today small to introduce a boiler with auxiliary devices. A boiler fuel supply role is to store, transport, supply of the fuel. There are coal, to the media devices (mill, of mill, and coarse powder separator and lose powder duct), and supply means (for the fuel heater and the like), a gas supply device and the like. Air blowing means which effect a treasure ah blower and duct, the grinding media and air into the furnace through the air preheater apparatus. Blower apparatus, comprising a draft fan and the smokestack, speaking furnace flue gas to exclude air sent. Water supply means comprises a water tank, water supply pipes and water treatment equipment, boiler feed water away. In addition to ash means ash comprising artificial addition, other mechanical ash, ash in addition to water, in addition to the negative pressure pneumatic ash, soot blowers, and other field ash, ash from the boiler and out away. Dust removing device, which includes a variety of dust action of gravity, inertial force, centrifugal force, washing bar-type, sound wave, filtering, static electricity, etc., fly ash out of the boiler flue gas, to protect the environment. Instruments, automatic control devices and valves, including the role of pressure gauge, a thermometer, a water level gauge, the alarm level, the relief valve, water meter, steam flow meter, pressure meter, indicating the exhaust of carbon dioxide and other instruments, a steam valve, a valve, a check valve, like the valve discharge valve, and automatic detection, automatic protection, control and automatic adjustment and automatic computer control means. The boiler more safe, economical operation. These are the auxiliary device structure of the boiler, I believe you must have learned a lot of knowledge of it, I hope this helps you make better use of boiler equipment.

The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary boilers need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.
