oil steam boiler

High Efficiency Oil Exhaust Gas Boiler with Air Vent Valves Descrition: The furnace and smoke side of boiler tubes absorb the heat produced by fired oil and transfer it to water, then the water will be evaporated into steam. Steam rise up and enter the vapor space because its specific gravity is reduced. The space left by steam will be made up by water with a heavier specific gravity. This process forms a natural steam-water circulation. When the water level becomes lower
