FIELD: environmental protection. SUBSTANCE: method comes to the following volume concentration of oxygen in exhaust gases is measured before afterburner and when pressure differential ΔPacross filter elements exceeds maximum tolerable value ΔP,, and oxygen concentration is below minimum value ([O]). exhaust gas flow is heated until pressure differential ΔPdrops below minimum tolerable value (ΔP).. Then delivery of additional fuel is stopped. It should be noted thanis preset function ofand T, and [O]is function of. EFFECT: enhanced reliability of operation of automatic filter reconditioning system, increased economy and service life of filter elements. 6 cl, 3 dwg |
