Abstract
A gas-fired boiler installation with control of the supply of combustion components, provided with a combustion space that upwardly is in communication with a boiler flue and at the bottom side is confined by a burner bed with atmospheric burners having interposed venturi tubes which upon throughflow by the gas controllably supplied via a valve, draw in primary air. Between the elements of the burner bed, from the bottom side thereof, secondary air can be drawn into the combustion space while the secondary air is controllable in conjunction with the control of the gas supply by a control valve.
Claims8
A gas-fired boiler installation with control of supply of combustion components comprising, in combination:
- a boiler flue;
- combustion space that upwardly is in communication with said boiler flue, the bottom side of said combustion space being confined by a burner bed having atmospheric burners horizontally positioned with interposed venturi tubes, which upon throughflow by the gas controllably supplied via a single valve, draw in primary air, and wherein, between the elements of the burner bed, from the bottom side thereof, secondary air can be drawn into the combustion space;
- and control means for variably controlling supply of secondary air in conjunction with variably controlling gas supply control, said control means for controlling supply of secondary air in conjunction with gas supply control including control adjustment means for said gas valve through which the gas is supplied, control adjustment means for a control valve for the secondary air and a driving unit, each of said control adjustment means being connected to said driving unit;
- whereby excess of air upon loads smaller than those at maximal capacity and their cooling affects are avoided.
