Pulverized Coal Boilers. Our pulverized coal (PC) boilers generate steam power for large-scale global power projects with up to 1350 MW electrical output for coal units at pressures and temperatures that enable net plant efficiencies of up to 50%. Our two-pass and tower boilers can reach up to 330 bar/ 650°C /670°C in both single and double
The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to

Boiler system (steam/water) loses water through steam and water leaks. Additional water called "make-up water" is added to the boiler to replace these losses. The amount of make-up water and the level of naturally occurring impurities in water will determine the type of water treatment required.
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
Oxygen attack in boilers. Without proper mechanical and chemical deaeration, oxygen in the feed water enters the boiler. Much is flashed off with the steam; the remainder can attack boiler metal. Oxygen in water produces pitting that is very severe because of its localized nature. Water containing ammonia, particularly in the presence of oxygen
Jan 15, 2021 · A boiler is a bit more complex than a forced air furnace in that it has more parts, valves, and controls. However, gas-fired boilers are fairly reliable and when problems do occur, they are usually related to the expansion tank or water circulation pump(s). The major components of the boiler for a hot water (hydronic) system include

Some older boilers may not have these relatively inexpensive devices. If a boiler does not have low-water trips, have these devices installed. Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted.
Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be
