Abstract
Abstract An improved compact heating system, particularly adapted for heating water and for steam generation, includes a combustible gas supply zone, a combustion chamber therearound in the form of a burner element comprising a refractory cup in heat exchange relation with an array of heat exchange elements spaced peripheral therefrom, and gas ignition means. The system is adapted to efficiently burn a high velocity stream of combustible gases and develop a wide range of B.t.u. outputs per hour, including multi-million B.t.u. outputs, while providing advantages of larger types of heating systems, including easy access for maintenance, repair, replacement and clean-up.

Claim 5
Dependent Claim
37 words
The improved heating system of claim 1 wherein said shield is spaced from said combustion chamber and fluid supply means and wherein blower means are provided for impelling gases through said system at a high flow rate.
Claim 6
Dependent Claim
65 words
The improved heating system of claim 1 wherein said burner element is a generally cylindrical and hollow cup with said combustion fluid supply means disposed centrally therein, wherein said fluid supply means is adapted to supply combustible gases, and wherein said heat exchanger elements are disposed in a generally cylindrical array around substantially the entire periphery of said cup to enclose said heat exchange zone.
Claim 7
Dependent Claim
41 words
The improved heating system of claim 3 wherein said system employs hot water as a heat transfer medium within said heat exchanger elements and combustible gases as combustible matter to said combustion chamber, and wherein said cup comprises stacked refractory discs.
Claim 8
Dependent Claim
63 words
The improved heating system of claim 1 wherein said heat exchanger elements are vertically disposed and are interconnected through spaced upper and lower headers at opposite ends thereof, and wherein a plurality of water return conduits are disposed peripheral of and parallel to said heat exchanger elements and interconnected therewith through said headers, whereby steam entrainment in said heat exchanger elementS is avoided.
Claim 9
Dependent Claim
54 words
The improved heating system of claim 4 wherein said cup is enclosed by the upper of said headers, wherein said cup is backed by thermally insulative material, and wherein said cup has a roughened inner gas-mixing surface, and wherein said lower header encloses thermally insulative material forming the base of said heat exchange zone.
Claim 10
Dependent Claim
86 words
The improved heating system of claim 6 wherein an air inlet duct is disposed in said outer heat insulative shield and communicates with said blower, wherein a gas exhaust duct is disposed through said shield at a point remote from said air inlet duct, and wherein said fluid supply means comprises a head connected to a gas supply duct, which head defines a plurality of orifices spaced to uniformly distribute combustible fluid along a substantial area of the base of said cup for uniform flame propagation.
