3 How Does EPCB Coal Fired Steam Boiler Work?

EPCB coal-fired steam boilers utilize a combination of a grate stoker, fire tubes, water tubes, and a dust catcher to efficiently generate steam by burning coal. The heat produced by the combustion process is transferred to the water, converting it into steam. This steam can then be utilized for various industrial processes, providing heat and power to different applications. The working process of EPCB coal fired steam boilers is as followed.

  • Fuel Supply: The fuel, typically coal, is supplied to the grate stoker from the coal scuttle. The grate stoker distributes coal evenly across the grate surface.
  • Combustion: The coal on the grate stoker is ignited, and the combustion process begins. The burning coal produces high-temperature smoke and gases.
  • Heat Transfer: The high-temperature smoke and gases pass through four pass fire tubes and water tubes within the boiler. These tubes facilitate the transfer of heat from the smoke to the boiler water. As the smoke flows through the tubes, the heat energy is absorbed by the water, raising its temperature.
  • Steam Generation: The heated water within the boiler reaches its boiling point, generating steam. The steam accumulates in the steam drum.
  • Flue Gas Outlet: The smoke and gases, after transferring their heat energy to the water, exit the boiler through the induced draft fan. The induced draft fan creates negative pressure, pulling the smoke into the flue system.
  • Dust Removal: Before the smoke is released into the atmosphere, it passes through a dust catcher. The dust catcher removes any particulate matter or impurities present in the smoke, ensuring cleaner emissions.
  • Chimney and Exhaust: The cleaned smoke is then directed to the chimney for release into the atmosphere. The chimney provides a safe and controlled outlet for the smoke, ensuring it disperses properly.

Compared with coal steam boilers, oil fired steam boilers offer several key features that making them a preferred choice for steam generation in various industrial and commercial applications.

4 What Is The Advantage of Coal Steam Boiler?

Coal fired steam boilers are designed for high efficiency, with optimized heat surfaces and burning devices. Our boilers feature a custom furnace design, strong grate design, and optimum dust inertia separation. The EPCB coal boiler’ robust and compact structure ensures easy installation and cost savings. These following advantages combine to deliver reliable and efficient performance in various industrial applications. 

4.1 High Efficiency

EPCB boilers are designed with an optimum heat surface and burning device, resulting in a heat efficiency that is 4% to 5% higher than the national standard. The boilers also feature excellent flue gas speed, which prevents ash deposition and abrasion on the heating surface. This allows the boiler to work at full load without the need for frequent soot-blowing, ensuring long-term high efficiency, and safety.

4.2 Custom Furnace Design

The furnace of EPCB coal-fired steam boilers can be customized based on the different fuel types, improving the burning rate of fuel and eliminating black smoke emissions. The boilers are equipped with independent loops and a specially designed injected circulation system for hot water boilers. The medium speed in the loop of the heat surface exceeds the national standard, enhancing overall performance.

4.3 Strong Grate Design

EPCB coal fired steam boilers are built with a robust and durable grate design. The grates are designed to be big and high-strength, ensuring reliable performance and longevity. Additionally, a rolling device is incorporated into the grate system, enhancing safety measures and reducing the possibility of coal leakage. This rolling device allows for convenient adjustment of the burning process, ensuring optimal combustion efficiency. The strong grate design in EPCB coal-fired steam boilers not only enhances their safety and reliability but also improves their overall operational efficiency.

4.4 Optimum Dust Inertia Separation

EPCB coal-fired steam boilers are equipped with an optimum dust inertia separation system at the furnace outlet. This feature efficiently reduces the concentration of exhaust gases and minimizes abrasion on the rear heat surface. The dust inertia separation mechanism ensures cleaner emissions and helps maintain the longevity of the boiler by preventing excessive wear and tear on the heat surface. By effectively separating and capturing dust particles, the boilers uphold high performance and maintain optimal efficiency throughout their operational lifespan.

4.5 Robust & Compact Structure

The compact structure of EPCB coal-fired steam boilers results in a smaller installation volume compared to other boiler types. This not only shortens the installation period but also lowers the cost of the boiler room.
