BOILER Russian patent published in 1995 - IPC

FIELD: heat power engineering. SUBSTANCE: boiler body is secured to the framework by means of stiffener rings and movable yokes 10 rigidly connected to them, the framework is made in the form of downcomers. The body accommodates furnace 3 and gas duct 4 separated by common screen 5, they are provided with front, side and rear screens 6 through 9.
