Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of increase in efficiency with increase in pressure becomes less as the pressure increases. A limit to the practicable operating pressure is set by the difficulty in separating moisture from steam in the boiler drum.

Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam. In other units, the flue gas is exchanged with boiler feed

In any study of waste heat recovery, it is absolutely necessary that there should be some use for the recovered heat. Typical examples of use would be preheating of combustion air, space heating, or pre-heating boiler feed water or process water. With high

Flash steam is a name given to the steam formed from hot condensate when the pressure is reduced. Flash steam is no different from normal steam, it is just a convenient name used to explain how the steam is formed. Normal or "live" steam is produced at a boiler, steam generator, or waste heat recovery generator – whereas flash steam

Industrial heating covers circulators, heat recovery, boiler shunts, pressure holding systems and much more. The one thing these applications have in common is that downtime must be avoided at all costs. For industrial heating systems, Grundfos supplies high-efficiency heat pumps as part of industrial heating solutions that ensure maximum

A heat recovery system can reclaim large amounts of energy during this essential process. Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems.
