Abstract
The invention relates to a method for heating an industrial furnace, wherein, apart from heating gas, a combustible process gas is also fed to a burner arrangement (9) of the industrial furnace for heating an interior space in the course of a heat treatment cycle. In order to optimize the use of the combustible process gas for the heating of the industrial furnace, the heat treatment cycle is split up into a plurality of process phases, wherein the supply of the process gas to the burner arrangement (9) is regulated depending on the process phase. Furthermore, the invention relates to a heating device (8) for an industrial furnace, as well as an industrial furnace that includes the heating device.
Claims14
A method for heating an industrial heat treating furnace comprising the steps of supplying a combustible process gas to a burner arrangement (9) of the industrial heat treating furnace and burning the combustible process gas to produce heating of an interior space of the industrial heat treating furnace during a heat treatment cycle, wherein the heat treatment cycle is divided into a plurality of process phases and the step of supplying the combustible process gas is regulated according to conditions in the industrial heat treating furnace during each of the process phases.
A heating apparatus (8) for an industrial furnace comprising:
- a gas line (14) connected to a process waste-gas outlet (13) of an industrial furnace or to a temporary process gas storage facility and to a burner arrangement (9) whereby a process gas can be conveyed from the process waste-gas outlet (13) or the temporary storage facility to the burner arrangement (9);
- and
- a gas flow control apparatus connected to the gas line (14) by which flow of the process gas to the burner arrangement (9) can be regulated depending on a process phase during a heat treatment cycle performed in the industrial furnace.
An industrial furnace comprising:
- a housing (1) that defines a main chamber (3) and a pre-chamber (4);
- a process-waste gas outlet (13) provided in the housing (1) so as to provide a gas flow channel from the pre-chamber (4) through the housing;
- and
- a heating apparatus (8) comprising:
- a gas line (14) connected to the process waste-gas outlet (13) and to a burner arrangement (9) whereby a process gas can be conveyed from the process waste-gas outlet (13) to the burner arrangement (9);
- and
- a gas flow control apparatus provided in the line (14) by which flow of the process gas to the burner arrangement (9) can be automatically regulated depending on a process phase during a heat treatment cycle performed in the industrial furnace.
