Abstract

One embodiment of a boiler system mechanical combustion air unit comprising a cylindrical main housing (102), a pressure sensing means composed of sensor cap (110) and sensor hole (124), a variable speed fan (104) and motor (106) driven by a variable speed drive (108) for moving a gaseous fluid at a variable volumetric flow rate, a temperature sensing means (114) for measuring the temperature of the gaseous fluid, and a controller (116) comprising a pressure transducer and electronic control. Other embodiments are described.

Claims

1. A boiler system mechanical combustion air unit, comprising:

a.) a fluid conduit enabling the transmission of a gaseous fluid,

b.) a means near the inlet of said fluid conduit for sensing the static pressure of said gaseous fluid,

c.) a variable speed fan system for moving said gaseous fluid,

d.) a means for sensing the temperature of said gaseous fluid,

e.) a controller in communication with said static pressure sensing means, and said temperature sensing means, and in communication with said variable speed fan system, the controller comprising electronic circuitry capable of controlling said variable speed fan system.

2. The boiler system mechanical combustion air unit of claim 1 wherein said sensing means is a hole through said conduit and covered by a rectangular cover.

3. The boiler system mechanical combustion air unit claim 1 wherein said variable speed fan system is a 3 phase motor with a variable speed three phase drive.

4. The boiler system mechanical combustion air unit claim 1 wherein said variable speed fan system is a DC motor with a variable speed DC motor drive.
