Waste heat recovery - Alfa Laval

Process heat from steam boilers. Recovering waste heat often reduces the need for steam in a plant. Consequently the boilers fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system. Recovered heat can also be used for preheating the boiler feed, lowering fuel consumption.

Recovery Boiler - an overview | ScienceDirect Topics

The steam jet also causes a heat shock when the deposit is knocked off. Typically sootblowers in the past used steam at reduced pressure after the primary superheaters, but now many boilers use steam extraction of the desired pressure from a steam turbine. Typically, sootblowers use 1825 bar pressure steam.

15 Ways To Increase Boiler Efficiency | Rasmussen Mechanical

Oct 01, 2018 · Recover Heat from Boiler Blowdown. Much like the return of condensate to the boiler, recovering the heat from the boiler blowdown can increase boiler efficiency. The blowdown valve is used to remove boiler water which contains soluble and insoluble solids. It helps reduce the level of dissolved solids in the boiler water to prevent boiler scale.

Heat recovery FAQ - Thermal Energy International

When replacing or adding boilers to a boiler plant, facilities have many options to consider, including replacing steam boilers with new steam boilers, or with condensing or noncondensing water heaters, or combining these options with heat recovery. The answer is not the same for all boiler plants.

Waste Heat Recovery Boiler| Industrial waste heat recovery system

Possible uses include heating of water, production of steam to drive turbines, and heating of public spaces. Pipes filled with fluid, known as heat pipe exchangers, are able to transfer heat and are used in situations where hot exhaust from kilns, furnaces and boilers can be recovered and used to warm air or water.

Which heat recovery auxiliary is used in a boiler? - Quora

Heat Recovery starts after the Flue gases exit the Main Pressure part which is at the Pressure and Temperature of Saturated Steam. Therefore the loss from the main boiler part is governed by the saturation Steam Temperature which governs the exit temperature alongwith combustion related losses.
