A reformer which may be included in a process plant, comprises a reactor chamber having a combustion chamber, to which fuel and combustion air are supplied. The exhaust gas from the combustion chamber may have a very high temperature, for example 650° C. The combustion chamber supplies heat energy to the reactor chamber in which a heat treatment of gas can take place. The process plant comprises at least one gas turbine. In order to reduce the consumption of energy, the exhaust gas discharge outlet of the gas turbine is through a channel, directly or indirectly, in fluid communication with the combustion air inlet of said combustion chamber, so that turbine exhaust gas preheated to a substantial temperature, e.g. 350-450° C., is blown through said channel, etc., through the overpressure of the turbine exhaust gas, e.g. of up to 0.5 bar, without the need for a fan, to the intake of the combustion chamber.
