Abstract
A regenerative combustion furnace system including a combustion chamber, a pair of primary regenerators, a pair of secondary regenerators, and a gas flow assembly. The gas flow assembly provides gas flow to and from each of the secondary regenerators which are in communication with each respective primary regenerator, and each primary regenerator is in communication with the combustion chamber. Each of the secondary regenerators includes a plurality of flues and a plenum. Each flue includes a primary regenerator port, a plenum port, and a variable position valve.
Claims9
A regenerative combustion furnace system comprising a combustion chamber, a pair of primary regenerators, each primary regenerator being in gas communication with said combustion chamber, a pair of secondary regenerators, each secondary regenerator being in gas communication with a respective one of said two primary regenerators, and gas flow means for providing gas flow to and from each of said secondary regenerators, wherein each said secondary regenerator comprises:
- a) a plurality of flues subdividing each said secondary regenerator;
- b) a plenum;
- c) a first connector means for connecting each of said flues to said plenum;
- d) a second connector means for connecting said gas flow means to each said plenum;
- and
- e) flow control means for varying the flow of gas between each of said flues and said plenum.
A method of regeneratively operating a combustion furnace system comprising a combustion chamber, a pair of primary regenerators, a pair of secondary regenerators, and gas flow means for providing gas flow to and from each of said secondary regenerators, wherein said method includes a first operational mode comprising the steps of:
- a) drawing combustion gas toward said combustion chamber through a first of said secondary regenerators and through a first of said primary regenerators;
- b) releasing ejection gas from said combustion chamber through a second of said primary regenerators and through a second of said secondary regenerators;
- c) dividing each of the respective volumes of flow of said combustion gas and said ejection gas through each of said secondary regenerators into a plurality of channels wherein each said channel includes a valve;
- and
- d) varying the positions of each of said respective valves.
A regenerative combustion furnace system comprising a combustion chamber, a pair of primary regenerators, each primary regenerator being in gas communication with said combustion chamber, a pair of secondary regenerators, each secondary regenerator being in gas communication with a respective one of said two primary regenerators, and gas flow means for providing gas flow to and from each of said secondary regenerators, wherein each said secondary regenerator comprises:
- a) at least three flues subdividing each said secondary regenerator;
- b) a plenum;
- c) a first connector means for connecting each of said flues to said plenum;
- d) a second connector means for connecting each said gas flow means to each said plenum;
- and
- e) flow control means for varying the flow of gas between each of said flues and said plenum.
