| Summary: | At a steam power plant coal-fired, Soot blower is a very important tool because it serves to clean the tubes on the boiler in Heat Recovery Area (HRA) are the superheater area, economizer, reheater, and the water heater from dirt / slag attached. Soot blower spraying hot steam auxiliary to clean the outside wall tubes and heat exchanger elements on water heater. Residue of fuel gas combustion in the boiler furnace is called flue gas. In the combustion flue gas still contains a lot of ash. Liquid ash contained in the flue gas will stick and freeze when the flue gas reaches the convection heating area in the HRA. Liquid Ash deposition would be very hard that known as Bird Nesting. While fly ash, the solid ash that drifting - kite follow the flow of flue gas will be stuck to the wall tube element of heat exchanger and air heater which will reduce the efficiency of heat exchange.
Soot blower working continuously in accordance with the schedule of periodic spraying scheme Soot blower. from the schedule of old scheme is obtained that spraying soot blower less effective. It is reviewed when there was an outage there was no slag / dirt on the Boiler. So need for an analysis about performance optimization of Soot blower on the boiler of steam power plant tanjung Jati B . The purpose of this analysis is to efficient the spraying process of Soot Blower by changing the schedule of spraying scheme periodic soot blower.
From the results of scheme changes process spraying of soot blower, obtained a new scheme of process spraying of soot blower is more effective. It is with steam saving of 366.53 tons / month and save the amount of coal consumption by 55 tons / month. Besides, it also can prevent the Boiler Pipe Erodied so it can make the tubes has more life time.
