Water heater with burner and two=part heat exchanger - has one part of heat exchanger in flame to extract hot flow and intensify flame

摘要

The water heater has a burner and a heat exchanger which consists of two units. The first unit (12) is located directly in the flame area to extract a hot flow between five and fifty per cent of the total hot stream. The design of the heat exchanger serves to optimise the combustion process while the remaining heat flow is transferred to the second exchanger unit (11). USE/ADVANTAGE - The flame in the water heater is stabilised and intensified to reduce carbon monoxide and nitrous oxide emissions.
