FIELD: coke production. SUBSTANCE: shelter 1 made as diffuser is provided with horizontal partitions 2 disposed on lower end of shelter and shutters 3 disposed in its upper part. Outer housing 4 has sealing elements 5 arranged on perimeter along which housing abuts on walls of sectioned coke carriage 9. A relationship is derived for determining shelter cross-section area taking into account aerodynamic and heat characteristics of coke drawing process. EFFECT: minimized amount of dust-gas-air mixture produced and decreased dimensions of aspiration system placed on door-extracting machine. 3 cl, 2 dwg
