Abstract
A wound boiler having an elongated hollow slab wound about a horizontal axis and the inner convolution defining a firebox and the outer convolutions defining a combustion gas passage leading to an exhaust.
Claims6
A wound boiler comprising,
- (a) an elongated generally rectangular hollow slab,
- (b) a heat exchanger intake port at one end of the hollow slab and communicating with its interior.
- (c) a heat exchanger outlet port at the other end of the rectangular slab and communicating with its interior,
- (d) the slab wound upon itself around a horizontal axis, in a plurality of convolutions with the intake port at the other end of the convolutions and the outlet port at the inner end of the convolutions,
- (e) a horizontal elongated firebox defined by the innermost convolution,
- (f) the innermost convolution and the next adjacent outer convolution disposed in spaced relation to each other and defining the entrance to a passage for combustion products to be conducted to a products-of-combustion passage,
- (g) successive convolutions disposed in spaced relation to each other and defining a products-of-combustion passage to be conducted to an expanded dimension exhaust gas passage,
- (h) an expanded dimension exhaust gas passage defined by the hollow slab at the bottom of the wound boiler,
- (i) the outer end of the hollow slab convolution joined to the adjacent inner convolution to define a longitudinal closure,
- (j) a combustion product's exhaust port communicating with the expanded dimension exhaust gas passage,
- (k) a closure at each side of the convolutions of the slab,
- (i) means for introducing combustion materials into the firebox through the closure at one side of the convolutions.
