2. Description of the boiler
The goal of developing the TKAN boiler was such that RADIJATOR INZENJERING could
offer the boiler to the market which is, according to its mechanical and thermal properties, distinctly
intended for biomass fuel.
Using the general term ‘BIOMASS’, it is, of course, thought of pellets, but the possibility of firing with
fruit pits, more precisely sour cherry and sweet cherry, should be pointed out as well.
If the user wants to use
some unlisted form of biomass, the construction and development department of Radijator inzenjering,
or the licensed seller should be contacted, because some specific types of biomass require special, specific
combustion solutions.
While using mentioned fuels, the automatic control of main operation parameters is
implied. With all listed examples of using biomass, a certain degree of fuel aridity is required.
On the other hand, market demands always lean towards even greater universality of fuel,
therefore TKAN can also be fired with wood and, then, firing is manual.
The furnace of TKAN industrial boilers is significantly smaller than in traditional boilers on
wood. Therefore, firing with wood and extracting ash is made harder. The conclusion is not to use
them when combusting huge amounts of wood and just for a couple of days. In these situations,
furnace shields and shields for ash cleaner screws should be used. They are represented in section
‘Starting the boiler on wood’.
In this situation, the combustion is done under the forced draft of the fan, therefore TKAN in
these conditions is more efficient than its predecessors which operate according to the free draft
principle.
Industrial boilers TKAN series are manufactured in the following powers: TKAN 60, TKAN
80, TKAN 100, TKAN 150, TKAN 200, TKAN 250, and TKAN 300.
CONSTRUCTION
Speaking of the external design, furnace dimensions, firing and cleaning holes, TKAN
preserved all good characteristics of previous models which distinguish RADIJATOR
INZENJERING on the market.
The water part of the boiler, its method of exchanging heat between flue gases and water
through the pipe exchanger, is adapted to biomass. Because of the fan, more precisely forced draft,
the route of flue gases is longer than in standard boilers. Due to the same reasons, it is possible to
flue gases deflectors, so-called turbulators that further increase the degree of utilization of the boiler.
Turbulators are spirals made of pipe-like material. If, while using, (chimney) there is too much smoke
on boiler doors in the firing phase or automatic controls system encounters difficulties when entering
the combustion phase, it is technically justified to use the boiler without turbulators (or with a smaller
number of).
