Boiler sootblower is one of important equipment to maximize steam boiler efficiency. Efficiency of boiler is influenced mostly by heat transfer process. One among the most necessary operations to increase heat transfer process is clean metal surfaces for absorb heat. The cleaning metal surfaces is performed to ensures appropriate heat transfer process and in addition avoids parts of steam boiler from growing to be plugged and blocked. Plugged parts could limit gas circulation and lead to load restrictions.
Boiler sootblower is specially needed on coal fired boiler and oil fired boiler. If oil fuel consist of low content of ash and generate small residue, the cleaning method of furnace wall can be performed by water washing for the duration of twelve-monthly shutdown. This is why; boiler sootblower which is installed on furnace wall is not needed on the oil fired boiler.
In the reheater and superheater parts of oil fired boiler, there’s ash accumulation on metal surfaces. Excessive-oil vanadium subject matter that contains chemicals to resist high-temperature corrosion, tend to be specifically vulnerable to the following. However while solid powder chemicals are utilized, the deposits of ash boost seriously in the high temperature of gas locations. The good thing is, the deposits fall and easily cleaned with boiler sootblower.
Coal fired boiler need many sootblower which is installed permanently. Reasons like high content of ash and ash-fusion temperatures determine simply what exactly sootblowing area is needed. Boiler sootblower usually utilizes compressed air or superheated steam as medium to eliminate deposits, utilizing rotary or retractable types. The efficient blowing regularity varies according to slag accumulation; however a usual could be four until eight hours. The steam boiler parts such as reheater and superheater is suitable to use long retractable type of sootblower to clean radiant heat surfaces.
