Abstract: The invention relates to a regulating system for a gas burner. Regulating systems for gas burners are used for guiding a gas flow and a combustion air flow to the burner. The gas flow can be regulated depending on combustion air pressure. Pressure is measured in known regulating devices with the aid of a membrane, that is pneumatically. The pneumatic pressure measurement limits the scope of application of known regulating devices. In the invention regulating device, a sensor (16) is arranged between a first line (10) guiding a gas flow and a second line (12) guiding the combustion air flow, an electric or electronic signal (19) being generated by the sensor that is used to regulate the gas valve (11).

Abstract: A burner system with staged fuel injection includes a burner with a swirl generator (1) for a combustion air stream and device(s) for introducing fuel into the combustion air stream, wherein the fuel introducing devices include at least two separate fuel supply elements (4a, 4b) with groups of fuel outlet openings for corresponding premix fuel amounts, wherein a first group is arranged downstream from a second group. The burner system furthermore includes measurement value probes (8, 9) for measuring the pulsations and emissions of the combustion, as well as a control device (10) that controls the two stages (4a, 4b) for introducing fuel dependent on the measured measuring values. The burner system permits optimized operation of the system even under changing operating and environmental conditions.

Abstract: A wood burning stove in the shape of a barrel having both primary and secondary air inlets for supplying clean combustion. Primary air is fed into the stove from above the door. Secondary air is fed into a heating duct which extends along the bottom of the stove to be preheated. The heating duct empties the preheated air into a plenum formed in the end of the stove remote from the door. Air admitted to the plenum is additionally heated by exposure to a series of heat transfer fins within the plenum. The shape of the plenum is such that the velocity of air in the central portion of the plenum is the slowest, allowing for efficient heat transfer from the plenum walls and fins to the air passing through. A baffle mounted in the stove above the fire shields the fire from the exhaust outlet. Secondary air is admitted into the interior of the stove from the plenum from a first set of ports near the top of the plenum.
