Steam boilers are common and important pieces of equipment in the industrial field, playing a vital role in many industries. Let's understand the working principle, structure, and classification of steam boilers.
Working Principle
The working principle of a steam boiler is relatively simple and efficient. First, fuel (such as coal, air, or biomass) is burned in the combustion chamber, producing high-temperature flue gas. This flue gas flows through water pipes inside the furnace wall, heating the water and converting it into steam through heat transfer. After steam is generated, it is delivered to equipment or systems that require steam, providing heat energy or power for industrial processes. After heat transfer, the steam cools, is discharged, and is converted back into water, which is then reheated and circulated. Utilization.
Structural Formation
A steam boiler consists of the following main components:
Furnace: The combustion chamber where fuel is burned, producing flue gas and combustion residue.
Furnace Wall: The furnace wall contacts the boiler's water tank, transferring heat to the water in the water pipes.
Water Pipes: Water pipes are tubes or bundles of tubes that hold water and receive heat. The heat converts the water into steam.
Steam Space: The area within the boiler where steam is generated and accumulated.
Flue: The flue guides flue gas from the furnace to the flue gas shield or flue gas treatment system.
Control System: A system used to monitor and control the boiler's operation, including monitoring and regulating parameters such as temperature, pressure, and fuel supply.
