Energy Saving
HRSG Heat Recovery Steam Generator Waste Heat Recovery Boiler With
the concepts of sustainable development, Waste Heat Recovery Boiler
circular economy, energy conservation and emission reduction, and
low carbon economy put forward one after another, HRSG waste heat
boiler China's industry of heat recovery steam generation has
developed from scratch.
Heat recovery steam generation refers to the technology of
converting surplus heat energy generated during the production
process into electric energy. Waste heat power generation is not
only energy-saving but also conducive to environmental protection.
Energy Saving Recovery Boiler The important equipment for Waste
heat power generation is the HRSG.
heat or combustible media inside
It uses heat or combustible media inside such working fluids as
waste gas and waste liquid as heat sources to produce steam for
power generation. Water wall header is the working media
temperature is not high, the boiler is large in volume and consumes
much metal. HRSG waste heat boiler
The waste heat used for power generation mainly includes the
residual heat of high-temperature flue gas, chemical reaction,
waste gas, waste liquid, low-temperature wastes, which are lower
than 200℃, etc.
At present, the application fields of waste heat power generation
have also been expanded to the steel, cement, glass, non-ferrous,
chemical and other industries combustion.
Water Wall Furnace Advantages
- It is good to adopt top supported water cooled wall and it could
reduce the load of boiler framework, which is benefit to overhang.
- Compared with the bare tubes, the membrane water wall improves the
heat absorption capacity of tubes.
- The factory direct boiler membrane water wall could improve the
Preliminary combination degree of boiler parts and reduce the
installation workload.
