초록 ▼

An improved burner for both liquid and gaseous fuels in which the combustion air is divided into at least two parts, comprising primary and secondary air. The primary air, which is insufficient to completely burn the fuel, creates a flame zone in which there is a deficiency of air, which produces quantities of carbon monoxide and hydrogen. The combustion products are recirculated, cooled and re-entered into the combustion zone in the region of the fuel and primary air entry, resulting in a reduction in the oxides of nitrogen. The secondary air, in quantities greater than the primary air, is introduced into a second combustion zone downstream of the first combustion zone. In the second combustion zone the deficiency in air is made up by the secondary air so that complete combustion can be carried out. If desired, a third quantity of air can be introduced still farther downstream in the flame zone.

대표청구항 ▼

A fluid fuel burner designed to produce minimum quantities of NOx, comprising: a. a nozzle for injection of fuel into a first combustion zone surrounded by a first ceramic tile, and means to supply said fuel under pressure to said nozzle; b. means adjacent said nozzle to supply a limited volume of primary air in the region of said nozzle, the volume being insufficient for complete combustion of said fuel; c. an enclosure means surrounding and spaced from said first ceramic tile to define a first annular space communicating the outlet of said first combustion zone with the region of said nozzle; d. means to recirculate a portion of the products of combustion from said first combustion zone around the outside of said first tile through said annular space to the vicinity of said nozzle; e. a cylindrical wall annularly spaced from and surrounding said enclosure, said wall having openings therein to supply therethrough air, a portion of which becomes said volume of primary air, a remaining and larger portion being secondary air; f. means to supply said secondary air in heat exchange relation with the outside of said enclosure means to cool said recirculated products thence to a second combustion zone downstream from said first combustion zone, the quantity of secondary air being sufficient to theoretically completely combust said fuel, said second zone surrounded by second ceramic tile; g. a second annular space surrounding said second tile in communication with the outlet of said second combustion zone; and h. means to supply tertiary air to said outlet of said second combustion zone via said second annular space.
