Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid. We can manufacture three types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer. H-finned tube economizer is high efficient heat exchanger economizer which is consisted of H-finned tubes.
Compared with bare tube economizer, H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes. It also can increase the flue gas flow area in order to reduce the flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high rigidness to fit long tube row.
The spiral finned economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion and short service time.
The function of the economizer is as its name implies, to "economize" or save on cooling costs. Obviously, it costs money to operate the compressor. If the compressor can be shut down and the system still provide adequate cooling, energy savings can be realized.
(1) HDB consistently executes successful boiler economizer installations using safe, cost-effective methods. Economizers improve boiler performance by increasing fuel efficiency and improving steam generation and response time.
(2) We can guide you through the process of installing or retrofitting existing boiler systems . Our expert boiler economizer and waste heat recovery system installations can reduce your overall fuel requirements, lower emissions, and ultimately reduce your boiler operating costs.
• Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.
• The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.
• Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.
• Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.
• Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp.stressing of the tube wall.
