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. The 10 ton gas fired steam boiler has a good fuel application, such as light oil, heavy oil, natural gas, liquefied gas, city coal gas and so on. And it has the following advantages: compact structure, small occupation area, good degree of flame; Good thermal insulation performance; With automatic burner, high combustion efficiency; Multiple protection function, safe and reliable operation; ISO9001-2008, IBR and ASME certifications.

Apart from national policies, ZG manufactured mixed biomass and coal fired dzh coal fired moving steam boiler is more Eco-friendly than coal fired steam boiler. Mixed biomass and coal fired steam boiler has widely fuel to burning such as bagasse and coal, rice husk and coal, sawdust and coal, palm shell and coal, etc.

"Can shipped on time, not only the ability to schedule Tianjin coal-fired boiler project and the Tianjin Municipal People spend time heating, but also on our fast boiler brand image, so we have to work overtime quality and quantity the coal-fired boiler complete product supply mission. "fast square to official said. Facing short construction period, heavy task difficult, we rationalize production processes, all front-line staff hard working, eventually will be shipped on time to the boiler Tianjin, and running. After the boiler in place, Tianjin coal-fired boiler project also completed the basic preparation, coal-fired boilers, Tianjin is also a blue sky will gradually improve and advance. Tianjin transformation of coal-fired boilers, fast Boiler contributed.

Main dzh coal fired moving steam 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.
