dzl steam coal industrial boiler

Reducing the project covers an area large steam dzl steam coal industrial boiler and therefore a large high-pressure steam boiler pipe insulation manufacturers buried heating pipe does not require masonry huge trench, just insulation pipe buried underground people, thus greatly reducing the project area, reducing earthwork open dig about 50% or more, reducing the amount of civil masonry and concrete 90%. Gas boiler, pipe insulation and processed in parallel trenching site, linker site only, shorten the construction period can be greater than about 50%, thermokeeping pipe is widely used a liquid, a gas pipeline network, Chemical Engineering Oil pipe insulation, the vapor Hence largest chemical boiler, central heating network, air conditioning and ventilation ducts, municipal engineering. Buried pipe insulation is one kind of good insulation properties, plus safe, reliable, low construction cost of the prefabricated buried pipe insulation. Effective solution incubated urban centralized heating with a high temperature heat input thermokeeping tube, sliding and water lubrication problems exposed tube ends. Buried pipe insulation not only has the traditional trench laying of pipelines and overhead incomparable advanced technology, practical performance, but also has significant social and economic benefits, but also energy-saving heating of effective measures. Prefabricated buried pipe insulation technology using buried heating pipe, marking polyurethane insulation heating pipe technology development has entered a new starting point. Reporters noted that this year again Yajian steel production capacity of about 50 million tons, quit more than 150 million tons of coal production capacity. Even the industry is expected this year to production capacity will be extended to glass, construction accounted for a large reduction in the steam boiler electrolytic aluminum, cement and shipbuilding industries. High pressure steam boiler pipe insulation manufacturers of polyurethane buried insulating pipe evacuated provided.

The final step is to select which type of steam dzl steam coal industrial boilers currently on the market have the type of fuel boilers, electric boilers. Due to the current state for the "coal to electricity," the advocate, more companies may choose an electric boiler, but there are energy consumption, safety issues such as the traditional electric boiler, by contrast, the crown than conventional electric steam boilers boiler energy saving more than 30% compared to conventional steam boilers have increased security.

Main steam dzl steam coal industrial 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.

AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam dzl steam coal industrial boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
