INFORMATION ABOUT COMBUSTION
In order to ensure correct combustion, as a general rule, the air
supplied to the fuel must be at a certain rate. So the fan speed
should be adjusted well. The air required for a certain amount of
fuel should not be too much. If the amount of air which is
changed depending on the type of fuel is less than the required
amount of carbon monoxide, the energy produced is reduced, the
combustion starts, the combustion efficiency decreases, the air
quantity is decreasing, the carbon monoxide decreases while the
non-combustion air is heated from the chimney by heating in the
furnace, the combustion is deteriorated and the combustion
efficiency It decreases.
If the temperature of the flue gas is above the accepted values, excess energy will be ejected from
the flue to the atmosphere. The material, the way of construction and the connection of the
chimneys are important in terms of high combustion efficiency, low heating cost and protection of
the environment.
The chimney must be good for burning to be good. It is recommended to use a high temperature
resistant firebrick and stainless steel chimneys. The horizontal smoke ducts should be connected to
the chimney with a slope of at least 5% and the length should never exceed 1/4 of the height of the
chimney. The height of the chimney should be well determined. The chimney sections must be
circular unless necessary.
Never use a hollow brick on the chimney walls. The most ideal is the creation of fire bricks.
ÜNMAK boilers must be connected to an
independent chimney that can provide the
minimum desired minimum traction.
Minimum traction is usually min. It should
be measured with a manometer in 20 Pa.
The part of the waste gas line between the
boiler and the chimney should be insulated
with glass wool. The waste gas pipe and
