Description

A non-powered pellet stove {wood pellet stove}

The present invention relates to a non-powered pellet furnace, and more particularly, to a non-powered pellet stove, and more particularly, to a method for introducing outside air into the interior of a pellet stove in order to enhance combustion efficiency of the pellet, So that the installation cost can be greatly reduced by a simple construction, and the heat efficiency can be increased. The present invention relates to a non-powered pellet stove.

Generally, pellets are produced by crushing plants and trees into small particles such as sawdust, compacting them into small granules by compressing them to a small and constant size without any adhesive, and they are widely used as fuel for heating and power generation.

These pellets are eco-friendly clean energy sources that replace fossil fuels such as coal and oil by not releasing harmful gases during combustion, which is an economical and environmentally friendly fuel as a renewable resource.

Particularly, since pellets have a similar calorific value to anthracite coal, they have a low ignition point, are easy to use, and are cheap. Therefore, when replacing diesel or anthracite used as heating fuel, fuel cost can be greatly reduced. Demand for radiators has increased significantly.

In recent years, as the burden of fuel cost has increased due to rising oil prices, there has been an increasing use of pellets made of wood as raw material in place of diesel or anthracite for the purpose of reducing fuel cost in factories or farmhouses that mainly used diesel or anthracite for heating In fact.

However, the conventional pellet furnace using the pellets as a fuel has a problem in that the heat of combustion is lowered because the combustion heat escapes directly through the combustion furnace opened upward.

Further, in the conventional pellet stove, since the fan rotated by the motor is rotated to increase the burning rate of the pellet, the outside air is forcibly introduced into the interior of the pellet stove. Therefore, for example, So that the combustion performance of the pellets is greatly deteriorated.

In the prior art, a pellet stove, which is a registered patent No. 10-1305400, has been proposed, in which a feed hole is formed at the base end of the feed tube, and air is supplied to the base end of the feed tube through the feed hole, In addition, since the air supplied to the proximal end portion of the transfer tube is blown toward the distal end portion of the transfer tube by the powder generated from the pellet introduced into the inlet of the transfer tube, the powder generated from the pellet is transferred It is possible to prevent the pellets from being prevented from being smoothly conveyed by accumulation in the inside of the pipe body.

However, in this conventional technique, since the means for supplying air to the proximal end portion of the conveyance pipe body uses an air supply fan that is rotated by the power of the motor, it can be used in an area or space where electricity is supplied, There is a problem that the air supply fan can not be used in the space and the burning rate of the pellet is lowered.

Further, in the case of the conventional pellet stove, a power supply means such as a supply fan or the like is provided, which has a problem of noise generated when a power means such as a supply fan operates.
