<p>The heating plant has a fuel cell arrangement and a parallel additional burner. Both are located in a common or two separate housing/s, formed as low pressure chamber/s. The housing has a common combined combustion air outlet pipe (10,17). The air and exhaust pipes (9,15,7,8) of additional burner and fuel cell arrangement, extend through a common collector (16), which is connected to the combustion air outlet pipe. The air pipe (9) leading to the additional burner is connected to the combustion air pipe (17) via a return valve (14) located in a dividing wall (18), through which the exhaust pipe also extends.</p> |
