Abstract

In every operation, every piece of equipment a Steam Power (power plant) has a very important role to support the continuity of the process of production of electric power. Reliability and resilience of an equipment in a generating unit is the responsibility of all employees are encouraged that work in the company. At one plant often found damage during overhaul and the unit is operating. Air Preheater is one such example, which often arise various problems with age operates. The pressure drop Lube Oil Pump into a new problem in the Air Preheater, the impact of these problems resulted in Air Preheater can not operate optimally, and the impact of the worst is a unit trip (shutdown), which means the unit stops to produce electricity because of the disruption in one engine plant, of course, it will cause harm to the company. Experience analysis, and manual book is a guide to solving problems every time a unit of power generation, as well as the precision and patience is needed to see clearly how the problem occurred.

Abstract

Suralaya Power Plant unit 1-4 using coal as fuel, before a coal burned in the living room fuel first crushed using pulverizer (mill).part of Mill has a function to alter the current round of torque electric motor is gearbox, in gearbox pulverizer there are gear - accessible teeth and safeguards that require lubrication circulation to minimize wears a so-called system lube oil pulverizer.When pulverizer are currently operating system and disturbance in lubricant oils pressure pulverizer resulting in low, then Mill stopped operating in tibatiba (trip). Mill trip will reduce coal supply toward boiler system, so that it will reduce the ability boiler in producing steam room and not directly affected electricity production.After understand pulverizer operations and system pelumasanya Because of that, in order to prevent pulverizer trip, the solution is menambahan gas reserves pemipaanya (piping) in pairs in parallel with pumps and will be operated if pressure lubricant low when pulverizer operate.pump and electric motor initiators suffers from specification is almost same or identical with valve isolation and valve system in the direction.pengabelan (wiring/cable length according) will also be modified to support pump operation reserves.
