Economizer Description:
The economizer is a steam generation system as like a boiler. when the exhaust gas discharge from the engine cylinder through the exhaust valve it goes to the boiler for generate steam by heating of water. After those gas it goes through the economizer the remaining exhaust gas temperature is heated the water in economiser. it help to generate steam, and it is improving the efficiency and save the fuel consumption An economizer uses the waste heat from the boiler exhaust, that would otherwise be lost to atmosphere to (in most cases) preheat the feed water into the boiler. This improves the boiler efficiency and reduces fuel costs. SAT-CHAM 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. 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.
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.
