Full Description

The waste heat boiler (WHB) is transferred to the process fluids such as water, air, steam, oil in gas-to-liquid and waste gas-to-gas which absorb heat from the exhaust of reciprocating Engines, Gas turbines, Furnaces, Incinerators, Marine, LNG vessel, Utility boilers, Cogeneration, Cement plants and other combustion process serviced in many Industries. The metallurgical of melting and annealing process , coke and coal treatment process, biomass fuel for fired steam raising process are also highly usable waste heat boiler.


The main applications are use in heavily fouled gas stream condition on the natural gas fired combine cycle power plant, WHB behind gas turbines are laid out according to the desired steam parameters. The heat which would normally be used it to create steam can be used to drive turbines which produce electricity.


The WHB are equipped with additional burners, the hot exhaust gas are used in the burner. This residual heat is recovered on the boiler, but may carry some particles. Therefore, the filtration system and cleaning devices are the most important equipment required to install.


Waste heat boiler design comprises two main types: fire-tube boilers (shell boilers), and water-tube boilers.


In fire-tube boilers, a steel shell encloses a water-filled space with metal tubes inside. Hot gases produced from a combustion process, such as inside a furnace, pass back and forth through the tubes transferring heat to the surrounding water.


Fire-tube waste heat boilers have the advantage that they are relatively simple to construct, install and maintain. The heat energy stored in the water can be used to respond to a short-term extra demand, although if all the heat is used there is the disadvantage that it will take a long time to replenish. Another limitation of this kind of equipment is that it cannot operate at the higher pressures a water-tube boiler can.


The water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases. In a reversal of the system inside a fire-tube boiler, waste heat, in the form of hot gases or furnace flames, surrounds the water-filled tubes. Insulating materials are used to protect the boiler tubes against flame damage. As well as tolerating high pressures, a water-tube waste heat boiler can respond quickly to changes in heat input.


Waste heat boilers can be improve the boiler efficiency for the usage of energy, as well as reduce the emission for the solution of environmental problems. It can reduce the fossil fuel consumption and financial running costs of a system.
