it is commonly used in industrial settings where large amounts of steam are required for various manufacturing processes. The steam boiler consists of a cylindrical shell with flue gas tubes passing through it. The natural gas is burned inside the furnace, and the hot gases produced flow through the flue gas tubes, heating the water in the shell. This process generates steam, which can then be used for various industrial processes such as power generation, heating, and cleaning. It is designed to be energy-efficient, with measures such as insulation to minimize heat loss and advanced combustion technology to optimize fuel usage. This results in lower energy costs and a reduced environmental footprint. Overall, a Gas fired 6000 kg/hr capacity IBR steam boilers high production capacity, safety features, and energy efficiency, it is an essential component of modern manufacturing.
