Production
Waste heat boiler is comprehensive utilization heat auxiliary
equipment, which is generally installed in the flue gas pass,
absorb heat (or waste heat) of exhausting flue gas to generate
steam, and to reduce flue gas temperature. If not mounted fan,
resistance of waste heat boiler is less than the total resistance
to pumping power of chimney. If mounted induced draft fan, induced
draft fan can only withstand less than 250℃ temperature, flue gas
temperature should be reduced to below 250℃, be sure to set the
waste heat boiler, in order to ensure the safe operation of the
heating system. If the waste heat boiler in the run-time failure,
and no by-pass flue, it will affect the normal operation of the
heating furnace.
Difference between waste heat boiler and the general boiler is,
waste heat boiler do not need fuel, but to use waste heat to
generate steam, so although a large investment for one time, but if
the steam can be fully utilized, then most of its investment can be
get back in 4 to 6 months. For the normal boiler, The flue gas
temperature is low, so the requirements of the heated surface is
much larger than the general boiler.
And the present stage, we can provide kinds of HRSG boiler as
bellow:
- Municipal solid waste incinerator(MSWI)
- Straw burning boiler
- Biomass Boilers
- Waste heat recovery unit gas turbine
- Low temperature HRSG boiler for dry cement kiln
Technical characteristics
Kiln (AQC) HRSG Features
1, Modular assembly structure, reliable sealing expansion
2, Adopt wear fin tubes, boiler pressure parts life assurance
3, Unique flash technology, the boiler outlet temperature is
reduced to below 90ºC
Kiln (SP) HRSG Features
1, Heating surface tubes and headers with privildged connection
structure, reducing mechanical shock and vibration
2, By mechanical vibration cleaning mode, continous cleaning mode
little impact on system operation
3, Set sealed scraper gray machine, greatly reducing dust tail.
