FIELD: process engineering.
SUBSTANCE: invention relates to throttling stabiliser of flue draft furnished with explosive valves. Invention aims at saving fuel resources, eliminating abrupt pressure surges, i.e. negative and positive overpressures, caused by "Zhukowsky water shock" in smoke removal systems. Proposed throttling stabiliser comprises casing with rigidly fixed bottom, top and rear surfaces. Casing side surfaces represent lay-on covers that can be displaced relative to said casing. Rectangular-shape throttle is arranged at casing front surface to revolve relative to mirror axis located along throttle mirror axis and secured thereat. Casing rear surface is furnished with rigidly secured bolt-on flange for attachment to said flue.
EFFECT: fuel savings, elimination of overpressure surges, longer life of boiler equipment.
