Wide Use Of Boilers

Boiler is an important heat supply equipment in national economy. Electric power, machinery, metallurgy, chemical industry, textile, papermaking, food and other industries, as well as industrial and civil heating require the boiler to supply a lot of heat.

A boiler is a device that uses the heat or other energy released from a fuel combustion to heat a working medium (the intermediate heat-carrying body) to a certain parameter. The boiler, Boiler Stoves which is used for heating water to convert it to steam, is called a steam boiler, also known as a steam generator. The boiler, which is used for heating water to improve the temperature into hot water, is called the hot water boiler and applied to heat the organic heat carrier as the organic heat carrier boiler.

From the point of view of energy utilization, boiler is a kind of energy conversion equipment. In the boiler, the chemical storage of an energy (fuel) can be transformed into the heat energy contained in the combustion product (flue gas and ash slag) through the combustion process, Boiler Stoves which is then passed through the heat transfer process to the intermediate heat-carrying body (e.g. water and steam), relying on it to transfer heat to the heat equipment.

The intermediate heat transfer of this heat is two of energy, Boiler Stoves because it is used to provide energy to the power equipment. It is called "working quality" when the intermediate-heat body is used for the heat transfer in the engine. If the intermediate heat transfer is only transmitted to the thermal device, Boiler Stoves providing heat for thermal use, it is often referred to as "heat medium".

Boiler according to its use can be divided into power station boilers, industrial boilers, marine boilers and locomotive boilers, such as four categories. The first two classes are also known as stationary boilers because they are mounted on a fixed basis and are not removable. Boiler Stoves The latter two types are called mobile boilers. This book describes the fixed-type industrial boilers.

There are three main processes in the boiler:

(1) The fuel is burned in the furnace, its chemical storage can be released in the form of heat energy, so that flame and combustion products (flue gas and ash slag) have high temperature.

(2) High temperature flame and flue gas transfer heat to working medium (heat medium) through "heating surface".

(3) The refrigerant (heat medium) is heated, Boiler Stoves its temperature rises or steam into saturated steam, or further heated into superheated steam.

The above three processes are interrelated and simultaneous, realizing the transformation and transfer of energy. Along with the conversion and transfer of energy, the flow and change of matter are also carried out:

(1) Working quality, such as water supply (or backwater) into the boiler, and finally in the form of steam (or hot water).

(2) fuel, such as coal into the furnace combustion, the combustible part of the combustion and the original moisture into flue gas, the original ash content is residual ash residue.

(3) Air into the furnace, wherein oxygen participates in the combustion reaction, Boiler Stoves the excess air and the reaction of the remaining inert gas in the flue gas discharged.

The water FAW system, the coal a ash system and the wind two smoke system are three main systems of the boiler, the work of these three systems is carried out simultaneously.

The process of fuel and flue gas is usually carried out (including combustion, exothermic, slag discharge, gas flow, etc.) is always referred to as "furnace process", the water, steam this-1 side of the process (water and steam flow, endothermic, vaporization, soda separation, thermochemical process, etc.) is always known as "in-pot process."
