A radiant heater comprises:- a) a burner; b) ducting for supplying air to the burner, which air has been pre-heated by heat exchange with exhaust gases; and c) a fan for assisting the supply of pre-heated air to the burner. <IMAGE>
Description
A RADIANT HEATER
According to the present invention, there is provided a radiant heater comprising:
a) a burner;
b) duct means for supplying air to the burner, which air has been pre-heated by heat exchange with exhaust gases; and
c) fan means for assisting the supply of pre-heated air to the burner.
The present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Fig. 1 is a view of the burner duct part of a radiant heater;
Fig. 2 is a view of part of a reflector housing of the heater;
Fig. 3 shows end and side views of the burner end of the heater;
Fig. 4 is an enlarged view of the burner end;
Fig. 5 is an enlarged view from above of a burner unit of the heater;
Fig-. 6 is an end view of the reflector housing;
Fig. 7 shows views of how a tube of the heater is provided with a U-bend; and
Figs. 8, 9, 10, 11 and 12 show details of an alternative construction.
The radiant heater shown is in two parts:
A) A reflector, tube assembly and ducting.
B) A burner assembly
Features of the radiant heater are: i) The burner is a twin fan high-temperature
intake air unit with provision for
multi-fuel firing.
ii) The unit takes in preheated intake air through
the lower duct which becomes fan assisted once
the incoming air is above 1200C. The air is
at optimum when it is running at 2000C.
iii) The hot air is mixed with the fuel at the
burner head and combustion takes place in the
tube.
iv) The hot products of combustion are devalued by
thermal transfer into the walls of the tube
which become hot and radiate energy (see for
example our Patent Applications Nos. 2148475
and 2145218).
v) The products of combustion travel down to the
'U' bend, which is of specific technical
design to achieve high thermal transfer, and
then they are pulled towards the exhaust
outlet of the heater tube by the exhaust fan
through the return part of the tube.
vi) The exhaust fan discharges the products of
combustion into an exhaust chamber which acts
as an upper level heat exchanger to the
incoming fresh air below. The exhaust heat
exchanger is connected directly to the exhaust
duct which runs above the intake duct as
shown.
vii) The exhaust duct and lower air intake duct
terminate either into a central ducting
system or in a balanced flue grill outside the
building.
As an alternative, a single air-inlet fan could be used (see Figs. 8, 9, 10, 11 and 12).
