AT8712U1 - BURNER FOR WOODEN BROKETS - Google Patents

Abstract

A combustion tube (1) with a base (2), an insert for holding the wood briquettes (3) and a base for holding the ignition material (4) are described. The invention relates to a burner for wood briquettes characterized in that the wood briquettes held in a stationary form, the wood is gasified in the burner and the resulting gases are burned above the burner.

Description Introduction:

The invention relates to a burner which burns the fuel (wood briquettes with -90 mm diameter) in a stationary form and which significantly simplifies or enables the lighting, the refilling of this fuel and the controllability of the performance of this burner.

State of the art according to fuel supplier: io example from Holzindustrie Pfeifer A-6460 Imst, Brennbichl 103 leaflet "Premium wood briquettes"

They take a piece of Förster wood briquette, break it into 2 to 3 slices and burn the 15 slices with Förster lighter. Then let the pieces burn evenly. Then fill the oven with Förster wood briquettes. Do not completely fill the oven, because there must be enough air supply.

Leaflet "Binder wood briquettes ... the intelligent fuel *

Wood briquettes expand when burned. It is necessary to make a filling according to the system. 25

Disadvantages of normal combustion:

The lighting of the briquettes time-consuming and laborious, usually only with the help of Anheizholz. In wood-burning stoves with glass pane, the pane becomes very sooty. A regulation of the heating power is very difficult or the exhaust gas values are very bad, because too little oxygen is supplied.

Object of the invention: 35 ignition of the fuel in the simplest way, attitude of the fuel, easy refueling, very good control of heating power, cleaning the burner very easy and burning out of the material to the minimum values specified by the manufacturer. The burner can be taken out to burn firewood. 40 Solution of the tasks:

The objects are achieved by the fact that by igniting (with a small piece of commercial igniter, which consists of a hydrocarbon mixture), the burner in a very short time reaches a temperature which is sufficient to the bound in the wood gases 45 and T eerdämpfe (from 150 ° C) release.

The ignition of these gases creates a clean gas flame above the burner.

Due to the further increase in temperature in the burner, the other substances bound in the wood, such as carbon (burns at 400 ° C), carbon monoxide, methane, acetylene and hydrogen (these ingredients require up to 750 ° C) are now released for combustion and burn in a gas flame above the burner.

Due to the precise feeding of the primary air, it is now possible to burn this burner in beliebiss gen power levels on the primary air supply without the high quality exhaust gas itself

Claims (2)

3 AT 008 712U1 immediately after the igniter burns down. In this burn, only a small amount of secondary air for afterburning and air purging the lens is needed. 5 A refueling of fuel is the easiest way and a re-ignition with minimal embers possible. The ash content is reduced to a minimum of -0.20% by burning in the combustion tube, which heats up to red hot. Effects of the Invention: This burner can be used in any heater which has a closed combustion chamber and has a combustion chamber height of 35 cm. Due to the simple control is the heating power through the primary air supply, the heat output is easily regulated and thereby exclude overheating of the rooms, thereby also a fuel savings of up to% is achieved. The performance can also be extended upwards by using multiple burners. 20 List and brief description of the existing drawing figures: A combustion tube 1 is welded to a base 2. An insert 3 which has the task to keep the fuel in a vertical position and to simplify the ignition. Ignition cube holder 4 is used for safe positioning of the ignition cube. Description of the Figures: A combustion tube 1 (wall thickness 1 mm) made of stainless steel 4301 with a height of 160 mm and a diameter of 120 mm is welded onto a base 2 with a base area of 135 mm × 135 mm × 30 mm. The base 2 is made of stainless steel 4301 (wall thickness 1.5 mm) and has a bore 35 in the center of 44 mm diameter. In the tube is an insert 3 which is made of 8 mm round steel (stainless steel) and has a height of 200 mm. 40 The round steel is bent 90 ° on the lower side and is welded crosswise. The clear diameter is 97 mm. On the curved round steel another round steel with a length of 25 mm is welded, which has the task of increasing the distance from the bottom of the base to the briquette 45 to ensure the ignition process. As Zündwürfelhalterung 4 is a perforated plate which is bent at an acute angle on the sides in order to simplify the placement of the burner and the detonator is securely positioned in the center. claims: 1. burner for wood briquettes, characterized in that the wood briquettes held in a stationary form, the wood is gasified in the burner and the resulting gases are burned above the burner. 55 4 AT 008 712 U1 2. Burner according to claim 1, characterized in that the combustion tube (1) with the Briketthalter (3) is installed directly in the furnace and that the ignition of these directly built-in burner is performed on the ashes. 5 1 sheet of drawings 10 15 20 25 30 35 40 45 50 55
