查询词典 steam engineering

According to the running state of the Boiler in Datang Huxian County Second Power Plant, the steam atomizing oil gun was reconstructed to the air atomizing oil gun. The compressed air was used to the atomizing medium of the oil gun that a great quantity of the steam was reduced when the boiler had been no running and steady boiling. Definitely the steam may be supplied by the steam turbine the fourth pulling out section,oil gun's use was not limited by the pressure of the atomizing steam at lower load. It has been realized the energy conservation efficiency function.
