One of the most important equipment of industrial facilities is the steam boiler, which is responsible for generating steam for industrial purposes and some facility systems. The boiler is actually an energy transfer or conversion system in which the energy stored in fossil fuels such as gas, diesel or diesel is converted into thermal energy. This device includes a closed combustion chamber where liquids are subjected to high temperature and pressure and become steam with high pressure. Steam is used in different industries with various temperature, pressure and applications.
✔️ How the boiler works
steam directly through the fuel consumed (coal, gas combustion, diesel, wood, etc.) or by using It can be produced from clean energy such as solar, nuclear, etc., and in an indirect way such as: recycling combined heat in processes or even equipment (gas turbine).

Generally, steam boilers are divided into the following 2 categories:
Fire tube boiler
water tube boiler
Of course, by using clean energy such as solar and nuclear energy in the relevant equipment (nuclear reactors), it is possible to produce super heat steam in large comparisons.
✔️ How the fire boiler works in the pipe
In this type of boilers, steam production takes place through the combustion of fuel in the furnace, and the fire or the gases resulting from combustion, passing through the second and third pass pipes, transfer their heat to water through the body of the pipes and the furnace. they transfer, they turn it into steam. These steam boilers are used in food and sugar industries, hospitals, rubber industries, etc., and the working pressure of super heat steam required in such industries is usually from 10 bar to a maximum of 25 bar.
✔️ How the water boiler works in the pipe
In the water tube boiler, the water in the connecting pipes between the upper drum and the lower drum is flowing and by receiving thermal energy from fuel combustion through radiation in the furnace and moving it in other parts, it turns into steam. These boilers (water tube) are used in industries such as refineries and power plants, when capacities higher than 100 to 1000 tons of steam per hour and higher working pressures of 30 bar (up to 200 bar) are needed.
