Abstract

Condensate water is the main ingredient in the process of generating steam in the power plant condensate water uap. Therefore must have a good quality so it does not cause damage to the equipment - equipment such as pipes, tubes, valves and others. To produce water quality condensate desirable it is necessary chemicals include phosphate, ammonia and chemical hydrasin. Material is injected into some equipment such as deaerator, steam drums and others. On this occasion the discussion is about the injection of chemicals phospat. Material the chemicals injected into the water condensate (feed water) which will be precisely in the boiler to the steam injection process takes drum. For pump chemicals from the tank in order to get to the steam drum. Therefore the pump and the output pipe leading the steam drum to be reliable so it does not interfere with the injection process resulting in the boiler water quality does not match the prescribed standards that disrupts the production of listrik.Namun on the way there has been a disruption especially at pipe outlet (discharge line) to the steam drum is clogged (plugging) .This occurs because after the injection process there are still remaining - the rest of phosphate in the pump, pipe valve outlet and then dries and crystallizes as kapur.This happens especially when the power is turned off for a long time (over houl). From the above problems it is necessary to add the channel for flushing (flushing) on ​​the pump and the discharge channel leading to the steam drum, especially when the power will be off for a long time so there is no plugging in the pipe leading to the pump outlet steam line drum. The addition of the plumbing connected condensate (from discharge CEP) to the pump inlet pipe phosphate.

Abstract

Coal power plant is designed based on a particular coal quality. Changes in coal quality will affect the quality of combustion and changes in combustion air. This study will describe the analysis of changes in coal quality on the ability of the force draft fan covers theoretical air, the percentage of air, capacity and force draft fan itself, and to analyze whether the capacity of force draft fan that existed at the time the design is adequate to the quality of coal that apply now .Berdasarkan calculation of theoretical air force draft fan air is 306 300 kg / s with the design power of 811 909 kW. Calculation of actual data shows the average air flow in the period from March to May was 307 610 kg of air / s. The capacity is still inadequate because of changes in the quality of the coal used is not too large.
