Basics of hot water heating boilers - Specifying Engineer

Sep 18 2020 · Heat from a combustion turbine or waste heat from a process can be directed to boiler. These are examples of external heat sources. Heat exchanger: Past the end of the flame zone the hot products of combustion and unconsumed portions of the air pass through narrower heat exchange channels and heat is transferred via convection and conduction. There are three main configuration of

What is a heat exchanger in a boiler? | Viessmann

To begin with the water was heated in the primary exchanger. As hot waste gases were produced the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger which only used waste gas to heat the water. Once it had been heated slightly in this heat exchanger it returned to the primary one to become even hotter. Viessmann boilers only contain one heat exchanger.
