ABSTRACT The purpose of this research is to explore and
test its several qualities of burner of the high-load water
heater under the different primary air and the different flame
orifice ratio. It uses Propane and Butane as the experimental
fuel of the water heater. It contains the degree of high-load
water heater , secondary pressure , the consumable fuel , heat
efficiency , input heat of fuel , excess air ratio , air-fuel
ratio and so on . Also we can observe and compare the color of
flame during its burn ing , and exploring the reason of
Lifting Flame , Flash Back Flame and Yellow Tip. We can
establish a system about all kinds of flame and exhaust by the
exhausted analytical equipment. The results show that it will
appear the Lifting Flame for Propane fuel when the primary air
is 45% and P2=190mm-H2O , λ=120.5%. Its exhaust gases are
located at all in the combustion range of safety . But for
Butane , when the Yellow Tip appears at the 25% of the primary
air and P2=175mm-H2O , λ=88% , the exhaus , the exhausted
value does not satisfy the CNS requirement. In varing the flame
orifice ratio , we can find the flame will get more stability
with the increase of the protecting-flame orifice. But for the
small flame , the phenomena of Yellow Tip will also obviously.
Therefore , the exhausted gas is not adequate to the CNS
requirement for the fuel of Butane when the flame orifice ratio
of forcing burning is at 1:5.85 and λ=74.5% , AF=54Keyword :
high-load water heater , flame orifice ratio , primary air ,
