A combined heat and power plant comprises an internal combustion engine (1); a steam boiler (4); a main line (3) which connects an outlet of the internal combustion engine (1) to an inlet of the boiler, for discharging gases from the internal combustion engine (1) to the boiler (4); a main line valve (5'), accommodated in the main line (3), for opening and closing the latter in a controllable manner; an air supply line (9) which opens out into the main line (3) downstream of the main line valve (5') and in which a fan (10) for supplying combustion air to the main line (3) is accommodated; an air supply line valve (11), accommodated in the air supply line (9) downstream of the fan (10), for opening and closing the air supply line (9) in a controllable manner; and a burner (12) accommodated in the main line (3) downstream of the air supply line (9). Upstream of the main line valve (5'), the main line (3) is provided with a blow-off line (14) which blows off into the atmosphere, and in which a blow-off line valve (15) is accommodated for opening and closing the blow-off line (14) in a controllable manner. The blow-off line (14) is designed to discharge at most the gas output generated by the internal combustion engine (1) at a blow-off rotational speed which is lower than the nominal rotational speed. <IMAGE> |
