Abstract
Provision is made to measure the heat of heater tubes in an external combustion engine and to control thereby as a function of changes of temperature the flow of air to the fuel burner. As the air supply increases the fuel supply is regulated. Thus as the load increases and the heater tubes cool more air and fuel is supplied to increase the heating to a desired level.
Claims3
A system for supplying fuel and combustion air to an external combustion engine with a combustion chamber operable with a predetermined proportion of fuel and air flow thereinto as temperature changes with variable engine loads comprising in combination, means for measuring the temperature of a high temperature part of said engine, governing means for adjusting the mass flow of combustion air fed to said combustion chamber of the engine in proportion to the difference between the measured and the desired temperature of said high temperature engine part, means for measuring the mass flow of air supplied to said combustion chamber comprising a turbulator nozzle supplying air into said combustion chamber and a pressure drop measuring device measuring the mass flow of air through said turbulator nozzle by sampling air flow inside and outside the combustion chamber, and means for supplying fuel in said predetermined proportion to the prevailing mass flow.
