FIELD: machine building. ^ SUBSTANCE: first combustion chamber (4) is used for one kind of fuel, while second combustion chamber (5) is used for another find of fuel. The second combustion chamber (5) is arranged above the first combustion chamber (4). The first and the second kind of fuel is the solid fuel and are of these kinds of fuel is the dry solid fuel. Second combustion chamber (5) is completely separated from first fuel chamber (4) by means of two-wall box (6) enveloping said second combustion chamber (5). Heat exchanger (14) is positioned over first combustion chamber (4) and second combustion chamber (5). First combustion chamber (4) has first stack (8), while second combustion chamber (5) has second stack (9); the said stacks are separated one from another. ^ EFFECT: high efficiency of combustion. ^ 10 cl, 1 dwg |
