The steam boiler has remained the cornerstone of several industries for 150 years. Steam Boiler manufacturers have profited from this expertise, even after 150 years of its discovery, in numerous fashions for different applications. From agriculture to automotive, from electricity generation to cement production, numerous industries have used this technology to great advantage. A steam boiler is a machine that uses heat energy to generate steam from water. Boiler manufacturers typically use wrought iron, and the cylindrically sized boiler generates steam by making use of a natural gas-fired burner. An industrial steam boiler has a low cost to construct and high thermal efficiency. They are also simple to use and operate, take up less space, and are inexpensive.
Use of Steam Boiler
The primary function of a hot-water boiler is to produce, store, and transport steam. Energy created from burning fuel heats water inside a cylindrical container, which produces steam at the desired temperature and pressure.The essential components of a steam boiler include a boiler, shell, valves, gauges, water level indicators, refectory, mountings, and so forth. The modern steam boiler produces steam at chosen temperatures, pressures, rates, and quality.
Types of Steam Boiler
A steam boiler can be divided according to its fuel types, size, principle, and application. Solid fuel and fluid fuel fired are classified.
-
Fluid Fuel Fired Steam Boiler
The oil and gas-fired steam generators have a very rugged design that permits fuel fluid to work. The steam boilers are very efficient and usually include a built-in device. Some of the top specifications for fuel fluid-fired steam boilers include
- Capacity 500 to 1000 kg per hour
- Steam Pressure 10 kilogram-square meter
- Efficiency up to 90
- Fuels Natural Gas, Furnace oil, LPG, Biodiesel.
-
Solid Fuel Fired Steam Boiler
The boilers using solid fuel fuel as a fuel look for the novel low moisture fuel with comparatively low content elements. These boilers are ideal for farms needing to operate additional turbines simultaneously or produce electrical power. Advanced technology components require minimal installation work. The primary specifications for a solid fuel boiler include:
- Capacity: 1000 to 2000 kg/hr
- Steam Pressure: 10-15 kg/cm2
- Efficiency: up to 80%
- Fuels: Sawdust, Coal, Wood, etc.
Types of Fuels used to operate the steam boiler
Steam boilers typically use fossil fuels to generate heat. Among the most commonly used kinds of fuels in steam boiler applications are :
- Coal
- Fuel Oil
- Natural Gas
- Biomass
Advantages of Steam Boiler
-
- High Efficiency : Steam has higher thermal conductance values than hot water or thermal oil systems. In comparison to hot water, the mass flow rate to transfer the same amount of heat in a steam boiler is 10-50 times smaller and 20-80 times less than the thermal oil systems.
- Modular design : Modular design makes it simple to raise the capacity of the system in a modular fashion. There is a portable design allowing maintenance and flexibility for multiple applications based on steam boiler use.
- High Performance : Due to the high- heat transfer coefficient, steam boilers require lower heat exchanger surface area during condensation, which results in reduced overall system cost. It is possible to achieve uniform and fast heating as steam grammatically releases large amounts of thermal energy at constant altitude. Similarly, it is possible to control temperature rapidly and consistently by adjusting the steam pressure.
- Environment Friendly: Thermal oil systems must manage heat transfer oils that have an adverse effect on the environment. As a result, these systems have required leak detection systems and special sealing in the pumps and valves. In addition, they require heat exchanges and fire-fighting systems. Steam boilers, on the other hand, are self-sustaining and environmentally friendly.
In summary, industrial steam boilers have been used to safely, reliably and efficiently generate steam for commercial, residential and industrial uses since the late 1800s. The primary components of an industrial boiler system include: The boiler, the explosion-proof pressure vessel or boiler shell, the steam piping, the feed-water system, and the method of conveying steam from the boiler to the application. The boiler system may include expansion tank, feedwater heater, and condensate return.
