pressure range of low pressure boiler

Boiler low load operation, why would vote with the upper burner? Most, high-pressure pressure range of low pressure boiler superheater is based on convective heat transfer based. As we all know, steam temperature characteristic is a convection superheater with decreasing load, the steam temperature drops. When the boiler load is low, there may be cases spray water control valve is fully closed, the steam temperature is still below the lower limit occurs. Although the furnace may take the method of increasing or outlet air ratio is increased to increase the furnace pressure boiler steam temperature, but these methods due to exhaust gas temperature is increased, increasing the excess air ratio of the exhaust. Causing heat loss increases, resulting in the boiler thermal efficiency.

10 tons of gas pressure range of low pressure boiler operation Notes

Generally speaking, gas steam boiler tonnage of large-scale food processing plants, chemical plants, breweries, paper mills and other production and processing enterprises need will be greater, so as to support production needs. Gas-fired steam boiler 10 tons, 20 tons and other tonnage is the preferred model.

So, condensing heat recovery waste heat recovery pressure range of low pressure boiler is how to achieve ultra-high thermal efficiency it?

1, different structures with ordinary gas-fired boilers, waste heat recovery condensing gas boiler addition of the condensing heat exchanger, economizer and air preheater, these facilities are recycled flue gas latent heat made adequate preparations.

2, burner structure is also different. Waste heat recovery boiler of condensing gas burner uses a split combustion engine, and in advance of the combustion air is heated by the air preheater, the heat released by combustion of the fuel is directly supplied to the boiler, to the combustion air need not be provided.

3, the condensing heat exchanger select stainless steel finned tubes, heat transfer rate is more than five times the ordinary boiler, heat better, longer life.

4, gas condensing heat recovery boiler also propose solutions to the nitrogen oxide emissions through the selection of target quality low NOx combustion engine to achieve low nitrogen emissions, is a pioneer in environmental protection.

Since the Shanxi provincial government issued "on the issuance of the People's Government of Shanxi Province, Shanxi Province to win the Battle of Blue Sky's three-year action plan", cities are actively responding to priorities and deployment. Jiexiu municipal government related departments have carried out remediation phase out coal-fired pressure range of low pressure boilers.

Future, Jiexiu City departments should fully understand the situation of air pollution prevention and control of the seriousness and urgency of initiatives to further strengthen the work, work harder to accelerate the phase-out of coal-fired boilers; comprehensive investigation to the use of coal-fired boilers, find out coal-fired boiler unit, boiler type and capacity, device status, etc. and establish a sound accounting boiler, cleaning up coal-fired boiler plant are out of range, so that base clear, the situation is clear, should be eliminated to make sure that eliminated; to clear objectives and tasks , responsible units, measures, in accordance with the time node in an orderly way, and effectively perform their duties, earnestly implement the clean alternative heat sources, the removal of coal-fired boiler with a new energy escorts to carry out work at the same time; to actively coordinate electricity, gas sector, as coal-fired boiler users to implement clean energy transformation provides safeguards to ensure that coal-fired boilers out of the objectives and tasks completed on schedule, and improve urban air quality, and gradually improve the quality of life of the masses.
