Two alternative schemes for waste heat recovery from flue gases of boiler type BKZ 220-100 in the Stepnogorsk TPP (Kazakhstan) are presented. The technical solutions are innovative because they create conditions for deep heat recovery even when using battery emulsifiers to purify the gas flow. A characteristic feature of the schemes is the purification of a small part (10-15%) of the stream by means of a bag filter and the mixing of the stream with the main gas flow consisting of moist gases after a battery emulsifier. An analysis and assessment of the technical and economic feasibility of the implementation of the two alternatives has been carried out.
