  • Balanced pressure solid fuel heating unit
    Patent number: 5522327
    Abstract: A method and apparatus for a pellet fuel burning heating unit for burning corn or wood pellets having a balanced pressure system having a four-way split combustion intake airstream. The invention includes a combustion air blower system for providing combustion air into a firebox containing a burner under positive pressure and at the same time providing a negative pressure to remove the combustion gases from the firebox. A pressure regulator and air splitter maintains a balance between the positive and negative pressure and adjusts the air flow into the firebox and out the exhaust. The exhaust is provided through a bank of exhaust tubes running from the top of the firebox to an exhaust manifold. The blower air moves into the pressure regulator and air splitter dividing the air flow such that a portion enters the heating unit exhaust manifold to produce a negative pressure and the remaining portion enters the heating unit burner under positive pressure.
