Abstract:
1. An apparatus for recovery of waste heat in a boiler system comprising: a closed vessel for heating liquid under pressure to create steam; said closed vessel connected to a steam utilizing device; said steam utilizing device connected to a steam trap; said steam trap capable of separating steam after use by said steam utilizing device from condensate; said steam trap connected to a feed water tank capable of receiving said condensate from said steam trap; said feed water tank connected to a feed water pump for pumping said condensate as feed water back into said closed vessel; said feed water tank having a heat exchanger therein; said heat exchanger having inlet and outlet connections to a water supply vessel, wherein said heat exchanger is capable of cycling water from and to said water supply vessel, such that said water cycled through the heat exchanger is not returned to said closed vessel; whereby heat loss when said feed water waits in said feed water tank to be pumped back into said closed vessel can be recovered to be applied for heating water cycled through said heat exchange from and to said water supply vessel.
