Energy Saving Measures for Natural Gas Steam Boilers

With the successive implementation of national energy-saving and environmental protection policies, traditional coal-fired industrial boilers have been gradually replaced by natural gas steam boilers, and a revolution has taken place in the field of energy saving and environmental protection in the industrial thermal power sector. In addition to converting traditional industrial coal-fired boilers to natural gas steam boilers, measures can be taken to save energy during the operation of natural gas steam boilers. The following are energy saving measures for natural gas steam boilers:

1, according to the amount of steam required for industrial production to reasonably select the rated power of the natural gas steam boiler and the number of boilers. The higher the match between these two conditions and the actual use, the smaller the exhaust loss and the more obvious the energy saving effect.

2, the full contact of fuel and air: the optimal ratio of combustion of the right amount of fuel and the right amount of air, you can improve the efficiency of the steam boiler fuel combustion and reduce the emission of pollutant gases, so as to achieve the goal of dual energy saving.

3, reduce the exhaust gas temperature of the natural gas steam boiler: reduce the exhaust gas temperature of the boiler gas steam boiler energy efficient renovation, and effective use of waste heat generated in the exhaust gas. Commonly used boiler efficiency of 85-88%, exhaust gas temperature of 220-230 ℃. If the installation of energy-saving devices and the use of waste heat, the exhaust gas temperature will be reduced to 140-150 ℃, the boiler efficiency can be increased to 90-93%.

4, the recovery and utilization of heat in the boiler effluent: continuous sewage in the heat through heat exchange is utilized gas steam boiler energy efficient renovation to improve the temperature of the itching water, so as to achieve the purpose of natural gas steam boiler energy saving.

At the same time, natural gas steam boiler energy-saving measures can also be reasonable recovery of condensate in the heating system, and recovery of heat from condensate.
