WHAT IS THE ELECTROSTATIC PRECIPITATOR

This article will discuss the application of electrostatic theories that have been discussed in previous articles here. Application of electrostatic in the industrial world are used to address the problem of waste dust. Among other industries that apply the power plant, sugar mills and cement plants, one way is to use electrostatic precipitator (ESP...

THE STEAM TURBINE

There are three (3) important things that should be known by an operator to operate the power plant or the Power House.                    1. SAFETY:                  a. Security for the people (person). In this case to avoid the things that   can cause an accident.                   b. Security for equipment (equipment) prevent damage to the equipment with respect to the implementation of the operation as recommended by manufacturer (Manual Book) as well as good maintenanc...

WHAT IS THE RECOVERY BOILER?

Definition Recovery Boiler Recovery Boiler A boiler is a special unit used to purify the compound - an organic chemical compounds contained in Black Liquor (waste cooking from the digester) and at the same time as high-pressure steam generator (High Pressure Steam). Heavy Black Liquor (70% solid) containing: An organic compound with the main content of Na2CO3, Na2SO4, NaOH, Na2S. Organic compounds derived from wood during cooking in the digester in the form of wood fibers, ligmin Water Heat energy contained in the Heavy Black Liquor range 3100 - 3500 kcal / kg dry solid. Heat energy is partly used to convert the organic compounds and partly used as fuel to generate steam Heavy Black Liquor Evaporator Vacuum produced by the input...

HOW DOES A POWER PLANT BOILER WORK

This time articel is i will study about how recovery boiler work. after yesterday I was talking about "THE ELECTROSTATIC PRECIPITATOR".The boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This part of the article series briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear. The Basics. Volume of one unit mass of steam is thousand times that of water, When water is converted to steam in a closed vessel the pressure will increase. Boiler uses this principle to produce high pressure steam. Conversion of Water to Steam evolves in three stages. • Heating the water from cold condition to boiling point...

MECHANISMS OF STEAM SOOT BLOWER EROSION

There are many mechanisms that can cause steam soot blower erosion of boiler tubes at various heat transfer sections. Knowing the way these mechanisms contribute to erosion will help to prevent loss of availability of boiler. Soot blowers are provided in boilers at various locations like water-walls, superheaters, reheaters, economizers and air pre-heaters. Steam soot blowers have specific advantage and disadvantages over other types. The advantages being mainly their low capital cost, operating cost and the effectiveness of cleaning in areas like furnace, superheaters and reheaters. The major disadvantages are they need a higher level of maintenance; effectiveness is low in oil firing mainly in air pre-heater area. They...

FURNACE CAMERA

This day i will taking about Furnace Camera.As the current technological developments in power plant technology especially the use of recovery boiler is constantly innovating in order to complement the existing deficiencies in the means of production to facilitate the operation of the recovery boiler. Currently the power plant that uses a recovery boiler there is a lack of technology to the unavailability of a device to control the conditions inside the boiler (furnace). So far the recovery boiler operator can only monitor the condition of the inside of the furnace manually just by looking at the field by controlling the air of room pannel (dcs). but that's not enough data taken with the actual data. accuracy conditions...

WHAT IS THE BLACK LIQUOR?

Concentrated black liquor contains organic dissolved wood residue in addition to sodium sulfate from the cooking chemicals added at the digester. Combustion of the organic portion of chemicals produces heat. In the recovery boiler heat is used to produce high pressure steam, which is used to generate electricity in a turbine. The turbine exhaust, low pressure steam is used for process heating. Combustion of black liquor in the recovery boiler furnace needs to be controlled carefully. High concentration of sulfur requires optimum process conditions to avoid production of sulfur dioxide and reduced sulfur gas emissions. In addition to environmentally clean combustion, reduction of inorganic sulfur must be achieved in the char bed. The...

NCG (NON CONDENSIBLE GASES)

NCG Burning in Recovery Boilers This time i will explain about Non Condensible Gases or NCG in Power plant boiler.after yesterday I was talking about "How does a power plant boiler work?" NCG = Non Condensible Gases NCG are: the non-condensable gas, this gas has a very distinctive odor karesteristik. This odor is caused by a mixture of sulfur into TRS (Total Reduced Sulfur) Categories A.Composition and NCG NCG content include: Hydrogen sulfide (H2S) Mercaptan (CH3SH) Dimethyl sulfide (CH3) 2S Dimethyl disulfide (CH3) 2S2 Ethanol (C2H5OH) NCG gases are divided into two categories, namely: LVHC = Low Volume High Cocentration High Volume Low HVLC = Cocentration B. Sources of NCG NCG is the fuel in the RECOVERY BOILER sourced from: A....
