May 04, 2021 · What is a heat exchanger? Suppose you have a gas central heating furnace (boiler) that heats hot-water radiators in various rooms in your home. It works by burning natural gas, making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. As the water pumps through the pipes, it absorbs the heat energy and heats up.Learn More

iii) Operation 1) Exhaust gas boiler circulation must be maintained at all times. This is to maintain tube temperature and prevent "cold end" corrosion of tube and fins. 2) Soot blowing to be carried out at least three times daily. 3) If it is necessary to stop circulation for any reason, the unit should be soot-blown prior to shut down.Learn More
