FIELD: power engineering; burning low-reaction solid fuels. SUBSTANCE: secured in upper parts of housings 1 and 2 is pipe line 3 supplying fuel to fluidized bed 4. Pipe line 3 is provided with exhaust branch pipe which is longitudinally located in housing 1. This branch pipe excludes entrapping of fuel into pipe line 10 discharging gas being generated and preheating fuel fed to fluidized bed 4. Housing 1 is mounted for longitudinal motion in housing 2, thus reducing stresses at areas of attachment of pipe lines 3 and 10 to housings 1 and 2. EFFECT: enhanced efficiency and reliability. 4 cl, 2 dwg |
