Product Description
Significant energy saving Cement kilns pressure HRSG heat recovery series with ASME standard
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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
