Abstract:

A boiler system including a first manifold, a second manifold provided at an elevation above the first manifold, and a heat exchanger conduit fluidly connecting the first and second manifolds. The conduit is provided within a first fluid flow, and the heat exchanger conduit receives a second fluid. A thermocouple is provided within the second manifold to measure a temperature of the second fluid within the second manifold. A control unit is provided to maintain a level of liquid phase of the second fluid such that liquid phase of the second fluid does not enter the second manifold based on the temperature measured by the thermocouple. The boiler system can be provided with first and second conduits, where the second conduit is provided within the first fluid flow downstream of the first conduit, and where the first and second conduits are inclined with respect to a vertical axis.
