Steam boilers are utilised in a range of different gas applications with this being a popular solution for hospitals, sewage treatment works and industrial process plants. Exhaust heat boilers are connected to the exhaust of the gas engine and can either be housed in an adjacent building or can be provided in their own customised container.
The fire tube single shell, single pass boiler is a simple, low cost solution for sub-critical waste heat boiler applications. Used when boiler steam quality is not a primary concern Design allows for small vapor space (limiting flexibility for handling rapid process condition changes)
Unfired steam boilers, that is, nominally termed “waste heat boilers” or “heat exchangers”, which generate steam by heat interchange with other fluids (see ASME code Par. U-1 (g)), should be equipped with pressure-relieving devices required by the ASME code, Section 1, as far as applicable; otherwise, refer Par. UG-125.
17-04-2020· A waste heat boiler of 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.
· PDF fileSteam boilers and waste heat boilers Steam is used in many industrial processes as an energy source and as a medium for carrying chemical substances. Typical application areas include the paper and building material industry, refineries, the pharmaceutical industry and the food processing industry.
Waste heat boiler design Waste Heat Recovery boilers are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust, Kiln exhaust, incinerator exhaust etc. to produce steam or hot water based on the application requirements of the plant. There are 4 basic requirements or inputs for calculating your waste heat from the source.
