Description

Field of use:

The The invention relates to a device for burning wood pellets in conventional Stoves from the manufacturer only for the firing with logs, briquettes and specially for it prepared fuel are provided.

State of the art:

to Time can Wood pellets only in specially for it prepared pelet / combi ovens are fired. conventional Fireplaces can only with logs / briquettes and specially prepared fuel burn.

Disadvantage of the prior art

In usual Stoves which are heated with logs or briquettes it is not possible Holzpeletts to burn these would due to its small diameter of about 6 mm and the low Length through fall the ashtray.

Even at pouring of wood pellets on an ashtray with small openings, where the pellets would not fall into the ash box that would be area on which the pellets stretch on the ashtray so big that the been poured Pellets within the shortest time Would burn time.

Combi ovens the with pellets and z. B. Logs u. Briquettes are fired usually much more expensive than stoves exclusively with logs u. Briquettes are fired.

Objects of the invention:

fuel a conventional one Stove of the manufacturer only for the firing with logs, Briquettes and for that Specially prepared fuel is provided with wood pellets.

solution the task:

Of the Fireplace insert is installed in the combustion chamber of the stove.

In The fireplace insert is filled with wood pellets.

These Wood pellets are lighted with the help of a fireplace lighter.

By a slider located on the bottom of the after burning the pellets open will be able to the spent wood pellets fall down into the ash pan.

Subsequently, will the fireplace insert refilled and the pellets lit again.

Advantages of the invention:

It it is possible instead of just logs and briquettes and specially made fuel also wood pellets in conventional Stoves to use for firing. The fireplace insert can from the combustion chamber of the stove and firing with firewood, Briquettes or for that specially made fuel is again possible. The burning time is depending on the capacity of the fireplace insert up to 2 hours.

Description of the invention:

Of the Fireplace insert is made of heat-resistant sheet steel, in which Regular intervals holes introduced become.

These vents serve better ventilation and thus contribute to a better combustion of Holzpeletts.

Of the Fireplace insert is open at the top to fill the wood pellets.

On the bottom is a slider which will burn off after the whole the pellets open becomes.

By that open The spent pellets fall down into the ash pan.

Of the Fireplace insert is on a console (in the drawing two pieces of rectangular tubes) placed.

In each of these tubes is pushed in another tube so that one stepless pulling apart and pushing together is possible.

These Telescopic tubes are adapted to the size of the combustion chamber customized so that the pipes rest on the right and left in the combustion chamber.

With one setscrew on the outer tube becomes the inner one Pipe detected so avoiding unintentional shifting becomes.

ever a pipe is at the back and front of the fireplace insert fastened by clamping screws. The telescopic tubes can also by another design, for the stove adapted to the stove, be replaced.

In the further development is provided the To close or open ventilation openings with the aid of a slide located on the outside of the fireplace insert in order to allow a controllable inflow of the air supply and thus a better combustion of the pellets.

It is provided to provide the fireplace insert with a holder which makes it possible remove the fireplace insert from the stove with the help of a pole without having to touch the fireplace itself.
