ÜKYP/YP Automatic Fuel Loading, Central System Heating Boiler Usage and Maintenance Manual
INFORMATION ABOUT COMBUSTION
In order to ensure correct combustion, as
a general rule, the air supplied to the fuel
should be at a certain rate. So the fan
speed should be adjusted well. The air
required for a given amount of fuel should
not be too much. If the amount of air,
which varies depending on the fuel type, is
less than necessary, carbon monoxide is
formed, the energy produced decreases,
the combustion starts, the combustion
efficiency decreases, if the amount of air is
more than necessary, the carbon
monoxide decreases, while the air that
does not enter the combustion is heated in
the furnace and thrown out of the
chimney, the combustion deteriorates, the
combustion efficiency is falling.
If the flue gas temperature is above the
accepted values, excess energy will be
thrown into the atmosphere from the
chimney. The material, construction and
connection of the chimneys are important in terms of high combustion efficiency, low heating cost and
protecting the environment.
In order for the combustion to be good, the chimney must also be good. Firebrick and stainless steel
chimneys are recommended as materials, with a smooth surface resistant to high temperatures.
Horizontal smoke ducts should be connected to the chimney with a rising slope of at least 5% and its
length should never exceed 1/4 of the chimney height. The chimney height should be well determined
and the chimney rising from the building
should rise at least 80 cm above the ridge.
Unless mandatory, chimney sections
should be circular.
Perforated bricks should never be used on
chimney walls. The most ideal is to be built
with fire bricks.
ÜNMAK boilers should be connected to an
independent chimney that can provide at
least the desired minimum draft. Minimum
traction is usually min. It should be
measured with a manometer as 20 Pa. The
part of the waste gas line between the
boiler and the chimney must be insulated
with glass wool. Flue gas pipe and chimney
must be made of steel sheet or material
