BOILER HOUSE Russian patent published in 2024 - IPC F22B33/18 F24D5/00 F22B1/18 

FIELD: thermal power engineering.

SUBSTANCE: group of inventions is related to embodiments of a boiler house, which in turn belongs to the field of thermal power engineering, where boiler houses and boilers are used to produce thermal energy for municipal, industrial and other consumers, including thermal power plants. An additional economizer section is introduced into a multi-section condensing economizer with sources of low-temperature coolants connected to the corresponding sections of the multi-section condensing economizer, which leads to additional selection of thermal energy from flue gases, which cannot be taken by useful heat consumers, and transfer its air mixed with flue gases after the condensing economizer, which significantly increases the thermal and economic performance, as well as the reliability of the boiler house as a whole.

EFFECT: objective of the group of inventions is to increase the energy efficiency of the boiler house while simultaneously preventing the formation of condensation in the chimney and exhaust pipe and maximizing the use of sensible and latent heat of flue gases, which can potentially be used by useful heat consumers, in particular water returning to the boiler, a heat pump, air supplied to the fuel combustion zone and for heating the premises of the boiler room, source water and chemically purified water to make up the boiler room.
