DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a method for the combustion of fuels in heating stoves displaying at least one front hatch, whereby the heating stove displays a fireplace with a hearth and ducts that communicate with a flue or an exhaust pipe, whereby a first duct or equivalent is disposed for discharge of flue or exhaust gases or residues thereof to the said flue pipe, which is disposed for discharge of the said flue gases or equivalent from the heating stove.
BACKGROUND
There is a need for heating stoves, in which flue and other exhaust gases produced are eliminated or reduced to a minimum for suppression of impermissible emissions of flue gases constituting a public nuisance. There is a furthermore a need in heating stoves for a better method of utilization of the heating energy generated for the heating of the rooms. For the purposes of heating, a long burning time is desirable in the stove, and in order to utilize the heating energy generated by the heating stove, the air in room should circulate through the heating stove, which circulation should be able to be controlled in order to make good use of the heating energy generated.
TECHNICAL PROBLEMS
Known heating stoves of the type in question do not fulfil the requirements in respect of exhaust gas emissions which are today being made with increasing frequency, especially with respect to their installation and use in heavily built-up areas. Thus the flue gases generated are discharged from the fireplace by being allowed to rise upwards in the combustion chamber and pass through a flue pipe which is disposed above the combustion chamber, whereby the inlet of the flue pipe is disposed above the hearth. Moreover, known heating stoves can only be supplied with a limited amount of fuel and thus require frequent filling with fuel during long-term heating.
THE SOLUTION
The utilization of a procedure in accordance with the present invention fulfils, however, the requirements made and suppresses the nuisances caused by the known heating stoves. Utilization of the procedure in accordance with the invention further confers a number of other advantages, which include a safe and optimum utilization of the heating stove also as a source of heat for heating purposes. Futhermore, the heating stove can be manufactured in a simple and safe way and at low cost, the latter contributing towards a readily available source of energy for energy conservation measures and one that is also easy to install. Naturally, the heating stove also fulfils such aesthetic requirements such as increased well-being and the like. In addition, the efficiency of combustion can be utilized in a more efficient aanner and thus be better employed for the purposes of heating. The procedure in accordance with the invention is characterised in that a second duct is disposed, which communicates with the flue or exhaust pipe and leads to the fireplace of the heating stove. In order to utilize the energy from the heating stove to heat the air in the room or to achieve purification of the flue gases or exhaust gases or residues thereof during the combustion of the fuel, the front hatch of the heating stove is closed, whereby a damper is made to cover or shut off the said second duct and the said flue gases or equivalent are thereby made to pass through the hearth of the fireplace or a bed of embers achieved on the hearth and are led to the first duct for discharge of the flue gases or equivalent to the said flue.
The invention also relates to a heating stove for the implementation of the said procedure, whereby the heating stove comprises both a combustion chamber, in which a fireplace with a hearth shall be disposed, and first and second ducts, which are disposed to communicate with the combustion chamber and a flue or exhaust pipe, which is disposed or shall be disposed for discharge of the flue or exhaust gases or residues thereof from the heating stove, whereby the combustion chamber displays a bottom, lateral walls and an open side towards the front side of the heating st
