Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion. This combustion takes place in the combustion chamber, and the …
Low-pressure boiler: The maximum pressure is 15-20 bar. It is used for heating purposes. Medium pressure boiler: The maximum pressure is 20-80 bars. It is used for power generation. High-pressure boiler: The maximum pressure is more than 80 bars. Sub-critical boiler: If the boiler produces steam at a pressure that is less than the critical pressure it is known as sub-critical.
The colder water gets pumped back to the process/equipment that absorbs heat or the condenser. It repeats the loop over and over again to constantly cool down the heated equipment or condensers. There are many different types of cooling towers but the cooling tower working principles stay pretty much the same. Phoenix, AZ 85040. Contact
installing condensing boiler alone does not guarantee achieving anticipated savings; careful attention must be paid to the boiler heating water system as a whole. Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F

On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.
