One of the reasonable countermeasures for the thermal efficiency of oil fired steam boiler is to adopt air preheater to develop direct expansion. However, the problem of choosing an air preprocessor is that it is very easy to produce ultra-low temperature corrosion of raw materials when sulfur content is used. So how can oil-fired steam boilers improve their thermal efficiency? Follow below Zozen Boilers together learn more!
As is known to all, oil-fired steam boiler boiler medium is water, the output medium is steam. Vapor may be divided into saturated vapor and saturated vapor. Gas steam boiler boiler medium for water, the output medium for the unsaturated state of boiling water. Special medium boiler Chemical plant fluid mechanics of boiler medium other than water, if there is a history of mercury liquid mercury silver gas steam boiler.
Increasing the total heat transfer area improves the furnace thermal efficiency. However, generally speaking, the total heat transfer area of the radiant segment has a moderate range due to the size of the grate or the appearance of the burner, and increasing the total heat transfer area of the radiant segment too much is not the best policy. Therefore, the method of raising the total area of heat conduction in the heat convection section is generally chosen, so as to achieve the goal of improving the thermal efficiency of the furnace.
One of the reasonable countermeasures to improve the thermal efficiency of oil-fired steam boiler is to adopt air preheater to develop direct expansion. However, the problem of choosing an air preprocessor is that it is very easy to produce ultra-low temperature corrosion of raw materials when sulfur content is used. According to the sulfur content in the natural material, a low temperature limit should be set for the metal temperature in the ultra-low temperature zone. Therefore, the smoke in the air - preheater inlet and outlet temperature also has a containment.
Select equipment temperature boiler is used from the boiler exhaust smoke waste heat calorific value to warm water or create steam. Set the temperature of this kind of equipment boiler is always the same as the amount of natural gas used in the hot coal oil furnace itself. The boiling water or steam generated by the equipment temperature boiler can be used for manufacturing and heating, thus indirectly saving natural gas. In the design scheme of this series of oil-fired boilers, the thermal efficiency of the furnace can be improved by reducing the excess gas rate of production capacity. In order to reduce excess capacity of gas rate, generally set gas channel separator, easy to carry out the adjustment of ignition gas. To the gas diesel or the natural gas type hot coal oil stove, may choose the low production energy surplus air gas type burner.
