Economizers are used to recover the useful heat in exhaust or flue gas before it is released into the atmosphere and transfer it to the steam production cycle. This increases the overall boiler thermal efficiency, resulting in more steam with less fuel.Get Price
Because of the fact that the nucleate boiling occurs around the furnace of firetube boilers, a further factor affecting the furnace metal temperature (besides firing rate) is the boiler pressure. It is for this reason that, in high-rise buildings, the boiler should either be located on the top floor of the building, or isolated from the building pressure by means of a heat exchanger.Get Price
