Use of condensing economizers with developed surfaces to improve the energy efficiency of conventional gas-fired heat generators in boilers

The current financial and economic programme in the Russian Federation is aimed at increasing energy efficiency all areas of society. most effective way boiler plant operation to improve technology deep heat recovery from heated flue gas chimney system hot-water boilers. physical essence this phenomenon consists cooling escaping high-temperature combustion products gaseous fuel, through contact with cold surface exchanger, a temperature below dew point under pressure convective bundle boiler. In regard, we set goal develop efficient design condensing economizer, which would allow us obtain fuel economy level generators. A practical model economizer for generators based on convection-type boilers has been created. study carried out, results conclude effectiveness its use individual local heating residential public buildings.
