Description
- 1. Field of the Invention
- This invention relates to a combustion system, more particularly to a combustion system including a heat exchanger separated from a furnace.
- 2. Description of Related Art
- U.S. Pat. No. 4,449,510 discloses a heat exchanger furnace that includes a furnace housing defining a combustion chamber therein, a plenum housing surrounding and cooperating with the furnace housing to define a plenum chamber therebetween, and a number of exhaust tubes disposed in the plenum chamber. A combustion gas from the combustion chamber of the furnace housing flows through the exhaust tubes along a serpentine path and into a stack. Meanwhile, ambient air passes into the plenum chamber, and is heated by contacting heat transfer surfaces of the combustion chamber and the exhaust tubes. However, the heat exchanger furnace thus arranged, i.e., the plenum chamber surrounds the furnace housing and the exhaust tubes are disposed within the plenum chamber, has a relatively poor heat exchanging efficiency between the exhaust gas and the heat exchanging air.
- Therefore, the object of the present invention is to provide a combustion system that can overcome the aforesaid drawback associated with the prior art.
- According to the present invention, a combustion system comprises: a furnace including a furnace housing defining a combustion chamber therein and having a gas outlet in fluid communication with the combustion chamber; a plenum housing surrounding and cooperating with the furnace housing to define a plenum chamber therebetween, and having an air inlet and an air outlet which are in fluid communication with the plenum chamber; and a heat exchanger having a heat exchanger housing disposed outwardly of the plenum housing, defining a heat exchanger chamber, and having an air inlet in fluid communication with the air outlet of the plenum housing, an air outlet, a gas inlet in fluid communication with the gas outlet of the furnace housing, and a gas outlet. The heat exchanger further has a tube-bundled structure disposed in the heat exchanger chamber and defining a plurality of passageways extending between and permitting fluid communication between the gas inlet and the gas outlet of the heat exchanger housing.
- In a drawing which illustrate an embodiment of the invention,
-
FIG. 1 is a schematic view of a combustion system embodying this invention. -
FIG. 1 illustrates the preferred embodiment of a combustion system according to this invention for combustion of solid waste, such as hull or shell waste of agricultural crops. - The combustion system includes: a
furnace 10 including afurnace housing 11 defining acombustion chamber 111 therein and having agas outlet 112 in fluid communication with thecombustion chamber 111; aplenum housing 61 surrounding and cooperating with thefurnace housing 11 to define aplenum chamber 601 therebetween, and having anair inlet 611 and anair outlet 603 which are in fluid communication with theplenum chamber 601; and aheat exchanger 50 having aheat exchanger housing 51 disposed outwardly of theplenum housing 61, defining aheat exchanger chamber 511, and having anair inlet 501 in fluid communication with theair outlet 603 of theplenum housing 61, anair outlet 502, agas inlet 503 in fluid communication with thegas outlet 112 of thefurnace housing 11, agas outlet 504. Theheat exchanger 50 further has a tube-bundledstructure 3 disposed in theheat exchanger chamber 511 and having a plurality ofexhaust tubes 31 which define a plurality ofpassageways 30 extending between and permitting fluid communication between thegas inlet 503 and thegas outlet 504 of theheat exchanger housing 51. - The
heat exchanger 50 further has a plurality ofbaffles 64 dividing theheat exchanger chamber 511 into a plurality ofsections 5111 which are connected to form a tortuous path extending between theair inlet 501 and theair outlet 502 of theheat exchanger housing 51. - A
manifold 22 interconnects thegas outlet 112 of thefurnace housing 11 and thegas inlet 503 of theheat exchanger housing 51, and extends through theair inlet 611 of theplenum housing 61. - During combustion of the solid waste, the combustion gas generated from the
combustion chamber 111 passes through themanifold 22 and into theexhaust tubes 31 of the tube-bundledstructure 3 and then into acyclone 23 connected to thegas outlet 504 of theheat exchanger housing 51 and finally into astack 8 connected to thecyclone 23 for emission of the combustion gas. Meanwhile, anair blower 242 is disposed downstream of theair outlet 502 of theheat exchanger housing 51 for introducing ambient fresh air via theair inlet 611 of theplenum housing 61 into theplenum chamber 601. The introduced air flows around thefurnace housing 11 for conducting a preliminary heat exchange, and then flows into theheat exchanger chamber 511 in a sinuous path across theexhaust tubes 31 of the tube-bundledstructure 3 for conducting a primary heat exchange. The heated air is then delivered into acrop dryer 7 for drying crops stored therein. - By disposing the
heat exchanger 50 outwardly of theplenum housing 61 of the combustion system of this invention, the heat exchanging efficiency between the introduced air and the exhaust gas can be considerably improved as compared to the aforesaid conventional heat exchanger furnace. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
