ABSTRACT:
An improved apparatus for heating fluid by burning liquid fuel is disclosed. To heat fluid such as water, air or the like medium heat exchanging is effected between the combustion chamber in which liquid fuel is burnt with combustion air introduced therein and the fluid passage through which fluid to be heated flows. The apparatus includes means for controlling rotational speed of a single motor for rotating the fuel pump and the blower, means for controlling a flow rate of fuel to be pumped from the fuel pump, means for controlling a flow rate of combustion air and an electronic control unit into which a variety of parameters relative to the above-mentioned means are inputted. The parameters are processed in the electronic control unit to individually control the means for controlling rotational speed of the motor, the means for controlling a flow rate of fuel and the means for controlling a flow rate of combustion whereby heat exchanging therebetween is achieved without fluctuation in temperature of fluid. Typically, the parameters are rotational speed of the motor and flow rate of fuel pumped from the fuel pump. The parameters may be those as selected from a group of atmosphere pressure, temperature of combustion air, voltage of electric current, temperature of fluid before and behind heating and required heating temperature of fluid.
