CHAUFFAGEKAR (Iran) presents new equipment at Aquatherm Moscow 2017!

08 Feb 2017


CHAUFFAGEKAR has designed and produced new devices made of stainless steel to introduce solutions, to increase boiler overall efficiency according to European Standards and regulations.

1. Economizer ENERGY SAVING:

This device is designed to perform as the independent exhaust gas condensation heat recovery unit for boilers with gas firing to use the sensitive and latent heat by cooling of flue gas to the condensation. This device is available in five sizes which can be matched to all conventional gas and oil fired boilers.

The flue system should be made of water pressure tight stainless steel construction which allows condensed gas to drain back to the collector in a reservoir at the base of the unit (A trap is provided to allow liquid to drop by gravity to a drain).

It’s been designed in form of standing fire tube, equipped with helical terbulators to increase the turbulence and heat transfer rate from flue gas to return water. At the moment we are exporting to European and Asian countries. This equipment is also meet Russian Market too.

 

In water side, this heat exchanger equipped with 2 baffles that create 3 flowing pass across the pipes and then producing uniform flow in the shell.

3. Measuring and Instrumentation Devices:

  • Gas Pressure Governor, Gas thermometer And pressure gage
  • Burner in use: Ray international Compact 2000 pressure jet type burner
  • Testo 350 M/XL Flue Gas Analyzer and Volumetric Gas Flow Meter

  • Installation Layout of boiler and condensing economizer
  • Increase in efficiency have very close dependency to return water temperature as seen as below:

  •  Computational Chart for energy Gains respect to water return temperature at various flue gas temperature based on 5 ℃ raised temperature in condensing unit.
