Generally, the exhaust gas boiler is installed in gas duct, generate steam by absorbing the flue gas waste heat, and decrease the exhaust gas temperature. Compare with the ordinary steam boilers, exhaust gas boiler do not burn fuels. It could change waste into wealth, has the advantages of energy saving and low production cost.
How about the calculation of the specific heat capacity for the exhaust gas? How to calculate heat of exhaust gases from a gas turbine ( We have developed a highly efficient boiler system
This calculator tool is used to calculate available heat for natural gas and other gaseous fuels that are primarily used by California industries. The available heat is defined as the amount of heat remaining in heating equipment (i.e. furnace, oven, boiler, heater, kiln etc.) after the heat
primary metals industries. Almost 78 percent of all boiler units use natural gas as a fuel. 56 percent of industrial boiler capacity is natural gas-fired, although certain industries (refining, paper, primary metals) have large shares of boiler capacity that are fired with by-product fuels.
For a range of natural gas compositions, encompassing the proposed European fuel supply standard, exact calculations of the stoichiometric flue gas volume are compared with the empirical EN 12952-15 calculations. The level of agreement is again very good. Validation on fuel oil has been limited to light fuel oils fired in gas turbines and boilers.
During the running of utility boiler, the flue gas oxygen content is one of the most important factors that affects boiler efficiency, and it affects each other with other thermal economic parameters such as flue gas temperature, unburned carbon in fly ash and slag and coal consumption of power supply.

The two most common forms of fuel for a boiler are gas and oil, with the former being the most convenient as the boiler can be fed directly from the mains gas supply. Wood burning boilers are available, however they require considerably more effort to maintain as the ash created by burning the wood needs to be disposed of regularly - which can be a considerable inconvenience.
In addition to the physical properties, the exhaust system designer must know certain other exhaust gas parameters. These include exhaust gas temperature—which is of special importance for the design of catalytic aftertreatment devices, as catalyst performance is a function of temperature—and exhaust gas flow rate.
