Abstract
A noise reduction plate for a thermal transfer device can include a body having plurality of apertures. The noise reduction plate is installed in the distribution channel of a premix blower and reduces ignition noise.
Claims20
A noise reduction plate assembly for a thermal transfer device, wherein the noise reduction plate assembly comprises:
- a premix blower comprising an air intake and a fuel intake;
- a distribution channel connected to the premix blower;
- and
- a noise reduction plate positioned within the distribution channel, wherein the noise reduction plate comprises a plurality of apertures.
1 more element
A boiler system, wherein the boiler system comprises:
- a premix blower comprising an air intake and a fuel intake;
- a manifold;
- a distribution channel fluidly connecting an outlet of the premix blower to an input of the manifold;
- a burner fluidly connected to an outlet of the manifold;
- a combustion chamber fluidly connected to the burner;
- a water inlet;
- a heat exchanger comprising a plurality of heat exchanger tubes configured to receive heated gases from the combustion chamber and wherein the heat exchanger is fluidly connected to the water inlet such that water from the water inlet moves through the heat exchanger and outside of the heat exchanger tubes;
- a hot water outlet connected to the heat exchanger configured to receive heated water from the heat exchanger;
- an exhaust fluidly connected to the heat exchanger tubes;
- and
- a noise reduction plate comprising a plurality of apertures, wherein the noise reduction plate is positioned between an outlet of the premix blower and the inlet of the mixing chamber.
8 more elements
A pre-mixed combustion system, wherein the pre-mixed combustion system comprises:
