Boiler Classification and Application Credit: 2 PDH

Combustion boilers are designed to use the chemical energy in fuel to raise the energy content of water so that it can be used for heating and power applications. Many fossil and nonfossil fuels are fired in boilers, but the most common types of fuel include coal, oil, and natural gas. During the combustion process, oxygen reacts with carbon, hydrogen, and other elements in the fuel to produce a flame and hot combustion gases. As these gases are drawn through the boiler, they cool as heat is transferred to water. Eventually the gases flow through a stack and into the atmosphere. As long as fuel and air are both available to continue the combustion process, heat will be generated.

Boiler operation

Type: This boiler is subcritical, once intermediate reheating and natural circulation steam drum boiler with overhung structure, balanced draft and dry-ash furnace, all-steel construction and outdoor arrangement.

Boiler Operation & Maintenance

Not many years ago boiler house was getting very little importance and was usually tucked away in some remote corner. Over the years the importance of the boiler has been realised and personnel operating this plant now need a high standard of skill and knowledge. This is mainly because major portions of the operating costs are incurred in the boiler plant. A boiler consumes a huge quantity of fuel, the cost of which has increased considerably. Every kJ of heat, which can be saved, lowers the cost and increases the efficiency of the station.

Boiler systems optimization

Boilers required a high amount of water to make hot water or steam for the industrial process. It is essential to pay attention to increase boiler efficiency and to mitigate the boiler common problems such as corrosion and scale formation. Different kinds of fuels are used in the boilers to supply the required amount of heat for steam production. Prioritization takes place for fossil fuel because of high calorific value. But in Sri Lanka, the use of biomass as fuel is most popular because it is considered a green energy source. In every industry, energy is wasting in various ways, as a form of heat, noise, friction, etc. That is the reason for all industries focused on energy management to reduce energy waste, energy costs while increasing efficiency. Then this article describes water treatment improvements, alternative fuel usage, energy management, and efficiency improving techniques in the industrial boiler.
