Pellets Centralheating Woodpellets
Company is a good Adress for
Centralheating Equipment in Newzealand!
Wood pellets which are clean,
pleasant smelling, environmentally friendly, natural, renewable fuel. Pellets
are made from sawdust and wood shavings, which are dried, compressed under
extremely high pressure and formed into small cylindrical 8 and 6 mm diameter
nor other kind of additives are used while manufacturing pellets. It is made
from 100% pure recycled wood waste. Making wood pellets helps to utilize wood
waste coming from sawmills, furniture produces and other wood factories.
resources have least influence to air pollution. Burning fossil fuel (coal or
oil) gives off big amounts of carbon dioxide, NO, SO2, HCH. Nowadays
one of the most important ecological problems is carbon dioxide, which effects
to the Earth temperature. Burning wood fuel also gives off some carbon dioxide,
but, as specialists think, it is neutral carbon, witch is a part of natural
cycle, it is balanced by the carbon absorbed by the growing trees.
All wood fuel
is natural, but pellets are dryer, humidity is less than 10%, while green wood
chips has about 45% and seasoned wood - 25% moisture content. The bigger
moisture content fuel has, the bigger amount of carbon dioxide gives off. That
means, that burning wood pellets gives off less carbon dioxide.
content is an advantage not only for air pollution, but also for our comfort.
Pellets are much easier to ignite, there's less tar build up in the chimney and
have bigger thermal value than wood chips or wood logs. It has considerable
advantage over other kind of wood fuel in terms of storage and transportation
are comfortable to use. There are lots of Pellet-Fired boilers and stoves
produced. Wood pellet stoves and boilers are automated and have automatic
ignition, thermostatic controls and can be operated on a time, which saves fuel.
It is similar to oil fired heating systems. Wood pellets are clean to use. It is
comfortable to use 20 kg bagged pellets in a household to fill pellet stoves.
fuel is clean and safe. There's no risk of explosion unlike oil or gas, no risk
of pollution if it accidentally releases. Wood pellets have minimal ash content
(less than 1%), wood ash is a good fertilizer and can be returned to nature.
Wood pellets fuel is clean,
comfortable to use fuel, which has lots of advantages in comparison with
fossilized fuel and other kinds of wood fuel.
ECOLOGICAL AND FULLY AUTOMATIC PELLET BOILERS
from HEIZ-TEC Europe
Twin Pellet and Wood-Boiler
Most of you already have some experience in using
wood or wooden briquettes for heating either in boilers or
fireplaces. These fuels are widely available at reasonably good
prices. A new product, not yet known by all, is the so-called
pellets, which are produced in a similar way as wooden briquettes by
high-pressure pressing of waste wood (dry sawdust and chips) without
any binder. It is predicted that in the near future the same
production technology shall be used to produce pellets from straw
and various biological wastes. The most frequently used pellet size
is with a diameter of 6, 8 and 9 mm and a length of
5 to 25 mm. The heating value is approximately the same as for
wooden briquettes, ranging from 17 to 19 MJ/kg. The price of pellets
produced by Newzealand producers, of which
there are currently more than fifteen, is ~
350 $ per ton. Pellets are currently supplied in
Newzealand in PVC bags (usually 15, 20 or 25
kg). Abroad, however, pellets are delivered in cistern trucks from
which suppliers fill any type of tank, as in the case of LTO (light
fuel oil). It is very important to store pellets in a dry place to
prevent their deterioration.
Our company has designed D20P
(22 kW output) pellet boilers and is preparing higher
Boilers are designed in such a way that the
HEIZ-TEC IWABO Swedish burner is
built into the left or right side of the boiler, functioning as a
heat exchanger, which draws pellets from the storage tank by means
of a screw conveyor. The fuel tank is located next to the boiler or
in an adjacent room and can be of any arbitrary size (the
standard size is 250 or 500 l).
The burner itself functions as follows. If the burner is
triggered (the need to heat arises), the conveyor pours pellets into
the burners spout and ignites them using a glowing coil. Following
sufficient pellet combustion, the burner is adjusted to the set
output where it remains until the system is heated. Thereafter, the
burner is switched off and pellets in the burners chamber are burnt
out. The whole cycle is repeated again when heating is required. The
boiler output and other burner functions are controlled
electronically, which enables an adaptation of the boiler operation
to specific system conditions. Addition of fuel, cleaning of the
burner combustion chamber and removal of ash is performed
once every 1 - 14 days, depending on the quality of pellets.
A great advantage of our pellet boilers is that the burner is
removed from the boiler and replaced by a lid, and wood can be used
to heat the system. These features mean that these boilers offer the
same degree of operating comfort and utility value as do boilers
running on gas, propane-butane or LTO. The main advantage is that in
comparison with natural gas or LTO,these boilers combust
renewable energy sources which makes their prospects look very good.
