1. Thermal Oil Boiler And Steam Boiler

Thermal Oil Boilers and Steam Boilers are two different types of industrial boilers used for various heating and power generation applications.

1.1 What Is Thermal Oil Boiler?

Thermal oil boiler, also known as thermal fluid heater or hot oil boiler, is a type of indirect heating system. They use a heat transfer fluid, often a synthetic or mineral-based oil, to transfer heat from a burner to the heating equipment. The heat transfer fluid circulates through a closed loop system, transferring thermal energy to the target process. 

Thermal oil boiler has the following characteristics.

Indirect Heating: The heat transfer fluid does not come into direct contact with the process material but indirectly transfers heat to it.

High Temperature Applications: Suitable for high-temperature processes, such as in the chemical, petrochemical, and manufacturing industries.

Precise Temperature Control: Allows for precise control of the process temperature.

Closed System: Operates in a closed-loop system, minimizing the risk of contamination.

1.2 What is Steam Boiler?

Steam boiler is the pressure vessel designed to convert water into steam through the application of heat. This steam can be used for various purposes, including power generation, heating, and industrial processes. Steam boilers are commonly used in industries such as power generation, chemical processing, and manufacturing. Steam boiler has the following characteristics.

Direct Heating: Water is directly converted into steam through the transfer of heat.

Versatility: Steam is a versatile medium used for a wide range of applications, from power generation to industrial processes.

Pressure Systems: Operates under pressure, with the steam produced at high pressures depending on the application.

Open or Closed System: Can be designed as either open systems (releasing steam to the atmosphere) or closed systems (condensing and reusing steam).

EPCB custom steam boiler solutions cover oil fired steam boiler, gas steam boiler,  coal fired steam boiler, biomass steam boiler,  industrial electric steam boiler, and more.

Closed-Loop System: Operates in a closed-loop circuit, minimizing the risk of contamination and ensuring a stable heat transfer process.

Precise Temperature Control: Enables precise temperature regulation crucial for various industrial processes.

3.1.2 Operational Processes of Thermal Oil Boiler

Heat Generation: A burner or electric heater raises the temperature of the thermal oil.

Circulation: The heated thermal oil circulates through a closed system, transferring heat to the target application.

Heat Exchange: The thermal oil releases heat in a heat exchanger, contributing to the production or processing of materials.

Return to Heater: The cooled thermal oil returns to the heater to be reheated, completing the closed-loop cycle.

3.2 Steam Boilers

3.2.1 Operating Principles

Direct Heat Conversion: Converts water into steam directly through the combustion of fuel.

Open System: Operates in an open system where steam is generated and released for various applications.

High-Pressure Steam: Can produce high-pressure steam suitable for power generation and industrial processes.

3.2.2 Steam Generation Process in A Steam Boiler

Fuel Combustion:

The steam generation process begins with the combustion of a fuel source, which can be coal, natural gas, oil, or biomass. The heat generated from this combustion is used to raise the temperature of water in the boiler.

Heat Transfer to Water:

The heat produced during combustion is transferred to water, typically contained in tubes or a vessel within the boiler. This raises the water temperature, converting it into steam.

Steam Formation: As the water absorbs heat, it undergoes a phase change from liquid to steam. This steam is then collected in the upper part of the boiler, ready for distribution.

Steam Distribution: The generated steam is directed to various applications. In industrial settings, it might be used for power generation, heating, or as a driving force for mechanical processes.

Condensation: After performing its work, the steam releases its heat energy to the surroundings or to a separate heat exchanger, causing it to condense back into water. This condensed water is then returned to the boiler for the cycle to repeat.

EPCB Boiler plays a important role in industrial processes by providing both thermal oil and steam boilers, facilitating efficient heat transfer crucial for various applications.
