1.2 What Are Main Components of EPCB Coal Steam Boiler

As an important representative of energy conversion equipment, coal fired steam Boilers play a vital role in industrial production. The design and assembly of its main components play a key role in the performance and stable operation of the boiler. Let’s take a closer look at the core components of an EPCB coal steam boiler. To ensure it performs optimally in various industrial applications, here is an overview of its main components.

1.2.1 What Is the Structure of Coal Steam Boiler?

Furnace: The furnace is the core part of a coal-fired steam boiler and is the space where fuel is burned. The inner wall of the furnace is made of refractory materials to withstand high temperatures. Coal burns in the furnace, transferring heat to the water.

Drum: The drum is the main part of the coal-fired steam boiler and is a cylindrical container. The inside of the drum is divided into two areas: the upper area is the steam area and the lower area is the water area.

Heating Surface: The heating surface is the part of the boiler that absorbs heat and is usually composed of many neatly arranged convection tube bundles. The water inside the tube is heated by absorbing thermal energy from the outer wall of the tube and is converted into steam.

Grate: The grate of a coal-fired steam boiler is a device used to support and fix the fuel (coal), prompting the coal to burn in the combustion chamber. The main grate types include: fixed grate, chain grate, and reciprocating grate. Each grate type has its unique advantages and applicable scenarios.

EPCB coal-fired steam boiler system, as a complex industrial equipment, consists of multiple major components that work together to achieve efficient steam generation. In addition to the boiler itself, EPCB will provide customers with a complete set of system configurations, including:

Pipe systems, chimneys (flues), control systems, dust removal systems, water supply systems, etc., these components work together to ensure that coal-fired steam boilers can operate stably and efficiently, providing the required steam for industrial production and processing, truly realizing One-stop service.

2. How Does A Coal Steam Boiler Work?

As a professional boiler supplier in the field of steam boilers, EPCB Boiler can assure you that the working principle of coal-fired steam boilers is complex but efficient.

2.1 Coal Combustion Process

The fuel supply system consists of a coal storage facility and a conveyor or feed mechanism that delivers coal to the combustion chamber at a controlled rate,then,fuel is ignited.

This flame heats the water in the pipes surrounding the chamber until it turns into high-pressure steam. This high-pressure steam is then transported through pipelines to various steam-consuming processes to provide steam and heat energy to industries.

2.2 How EPCB Coal Steam Boiler Generates Steam

EPCB Coal Steam Boiler, specifically designed for different industries, operates based on the same principles as other water-tube boilers. It efficiently converts coal fuel into heat energy, which is then transferred to water to generate steam.

In a Coal Steam Boiler, coal is burned in a furnace. The combustion of coal produces high temperatures, which heat the boiler’s water-filled tubes. The heat energy from the combustion process is transferred to the water through conduction.

As the water absorbs heat, it begins to boil and form steam. The steam produced in the boiler drum rises and separates from the water. It then enters the superheater, where it is further heated to reach high temperatures. The superheated steam is essential for various industrial processes and applications.

To ensure optimal performance and fuel savings, EPCB boiler’s Coal Steam Boiler control system is programmed according to the characteristics of different industries. It is designed to be adjustable based on user habits and conditions, allowing for continuous optimization of the system’s application process. This optimization aims to make the system more suitable for production in different factories, resulting in greater boiler efficiency and reduced coal expenditures.
