Abstract
In order to improve a method for determining the quickly changing, average temperature of a flow of compressible medium such that it is possible to ascertain sudden changes in temperature accurately and with the least possible delay in time, it is suggested that the medium be caused to flow through a throttle point, that the mass flow of medium flowing through the throttle point be determined, that the pressure inside and upstream outside the throttle point be ascertained and that the average temperature be determined on the basis of the mass flow and the pressure inside and outside the throttle point.
Claims9
A method for determining the quickly changing, average temperature of a flow of compressible medium within a conduit, comprising the steps of:
- providing a throttle point at an end of said conduit;
- passing said medium through said throttle point,
- determining the mass flow of said medium flowing through said throttle point,
- ascertaining the pressure inside and upstream outside said throttle point, and
- determining the average temperature of said flow of medium input to said throttle point on the basis of said mass flow and said pressure inside and upstream outside said throttle point.
A method for determining the average temperature of the steam issuing from a combustion chamber of a steam generator, comprising the steps of:
- reacting a fuel with an oxidizer in said combustion chamber and injecting water into said combustion chamber,
- providing a throttle point at an end of said combustion chamber from which the steam issues,
- ascertaining the mass flow issuing from said throttle
- ascertaining the pressure inside said throttle point and upstream outside said throttle point, and
- determining the average temperature of the steam issuing from said combustion chamber on the basis of the mass flow issuing from said throttle point and said pressure inside and upstream outside said throttle point.
