Description
Technical Field
The application relates to the field of ash removal devices, in particular to a boiler steam soot blower.
Background
During operation of the boiler, a large amount of ash is generated after the fuel is burned. Part of the ash is left in the hearth and discharged in the form of slag discharge, and the other part of the ash enters the tail part of the boiler together with the high-temperature gas flow. When the ash laden flue gas stream flows through the heat exchange surface at the tail of the boiler, part of the ash particles will deposit on the heat exchange surface to form ash deposits. As the heat conductivity coefficient of the ash is small, once the ash is deposited on the convection heat exchange surface, the heat transfer of the heating surface of the boiler is weakened, the thermal resistance of the heating surface is increased, and the heat exchange efficiency of the boiler is further reduced. When the heating area is seriously accumulated with ash and slag, the furnace can be accidentally shut down, and great economic loss is caused.
In order to prevent the appearance of above problem, need carry out the ash removal work to the boiler, traditional boiler ash removal work is gone on by the manual work, need carry out the blowing out operation to the boiler when carrying out the ash removal, then open the front and back manhole of boiler, the staff gets into the boiler and washes the boiler with the water, at this in-process, needs to carry out the blowing out processing to the boiler, still has caused the influence to production efficiency when leading to the fact workman intensity of labour to be big from this.
