1.Features Of Gas / OIl Fired Steam Boiler
It uses the most mature three-pass all wet back structure in the world. which safe and reliable. The use of waveform furnace can strengthen disturbance of smoke, increasing the heat transfer area of radiation, which can not only enhance the heat transfer effect, and also promote oil combustion in the furnace, the entire heating surface is in symmetrical arrangement with strong structure and reasonable system of water cycle. The water capacity in steam drum is large, with large steam room and quality steam and small fluctuations of water level in running. The unique setting of hearth and scouring way of smoke surface reduce the boiler heat loss to be minimal.
