What are the common types of boiler in thermal power plant?

Q: What are the common types of boiler in thermal power plant based on fuel?
A: In thermal power plants, boilers are classified based on the fuel they utilize:

1. Coal-fired Boilers: These boilers use coal as fuel, releasing heat energy that converts water into steam to drive turbines for electricity generation. However, the combustion process generates pollutants like sulfur dioxide, nitrogen oxides, and particulate matter.
2. Oil-fired Boilers: Utilizing liquid fuels such as oil or natural gas, these boilers offer higher combustion efficiency than coal-fired counterparts, with relatively lower emissions. They prove beneficial in regions with fuel shortages or stringent environmental regulations.
3. Gas-fired Boilers: Operating on combustible gases like natural gas or coalbed methane, gas-fired boilers are known for their clean and efficient performance, with lower emissions and convenient operation.
4. Biomass Boilers: These boilers utilize renewable resources such as agricultural and forestry waste or biomass pellets to generate heat energy. They not only meet energy demands but also contribute to carbon emission reduction, aligning with sustainable development principles.
5. Fluidized Bed Boilers: These innovative boilers are efficient and low in emissions, suitable for poor-quality coal and biomass fuels. By burning fuel in a fluidized state, these boilers significantly enhance combustion efficiency and effectively control pollutant emissions.

Q: What are the common types of boiler in thermal power plant based on evaporation capacity?
A: Boilers are categorized based on evaporation capacity in thermal power plants:

1. Small Boilers: Evaporation capacity below 75 t/h, ideal for smaller-scale power generation scenarios.
2. Medium Boilers: Evaporation capacity ranging from 75 to 400 t/h, meeting medium-scale power generation requirements.
3. Large Boilers: Evaporation capacity exceeding 400 t/h, primarily used in large thermal power plants to provide ample steam to drive high-power turbines.

Q: What are the common types of boiler in thermal power plant based on pressure levels?
A: Boilers can be classified based on pressure levels in thermal power plants:

1. Low-pressure Boilers: Operating below 1.0 MPa, featuring simple structures and lower costs, suitable for small power facilities or scenarios with low-pressure requirements.
2. Medium-pressure Boilers: Operating between 1.0 and 3.9 MPa, offering balanced performance for general industrial applications and some small-scale power generation needs.
3. High-pressure Boilers: Operating between 3.9 and 10.5 MPa, capable of producing high-temperature, high-pressure steam, ideal for large industrial production and specific power generation projects.
4. Ultra-high-pressure Boilers: Operating between 10.5 and 16.0 MPa, with higher steam parameters, commonly used in large thermal power plants to enhance electricity generation efficiency.
5. Subcritical Boilers: Operating between 16.0 and 22.0 MPa, featuring advanced technology and higher operational costs, leading to improved power generation efficiency.
6. Supercritical Boilers: Operating above 22.0 MPa, employing advanced technology to significantly enhance electricity generation efficiency, reduce energy consumption, and lower pollutant emissions, a preferred choice in modern large thermal power plants.
