Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or
Learn MoreWhat is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes.
