Abstract
Heat is reclaimed from a high temperature gasifier exhaust gas of between 250° C. and 20000C. A first duct receives the exhaust gas, and outputs it at a reduced temperature. A second duct receives a heat transfer fluid and outputs it at an elevated temperature. A heat transfer arrangement conducts heat extracted from the product gas to the heat transfer fluid (steam), thereby elevating the temperature of the heat transfer fluid. A heat pipe formed of sodium, potassium, rubidium, or lithium, has a first end for communicating with the high temperature exhaust gas and a second end for communicating with the heat transfer fluid. The heat pipe has an envelope formed of a selectable combination of stainless steel, Inconel, nickel, molybdenum, tungsten, niobium, carbon, carbon composite, and Hastelloy X, and a safety valve that ensures safe operation. An adiabatic zone is interposed between the first and second ducts.

- This invention relates generally to power generation systems, and more particularly, to a system for reclaiming high temperature sensible heat from the gaseous exhaust of a conventional or plasma gasifier arrangement.
- 2. Description of the Related Art
- In the current energy environment there is increasing desire to use renewable, or carbon neutral, energy sources. In the process of using these energy sources gasification processes are commonly used to produce syngas. Sometimes plasma is used for the gasification heat source, resulting in syngas exit temperatures that routinely reach 1250° C. Occasionally, higher exit temperatures are achieved depending upon the characteristics of the feedstock being consumed and other process variables. It has been a challenge to reclaim this high temperature sensible heat energy without resorting to complex systems of the type presently used in the nuclear power industry.
- It is, therefore, an object of this invention to provide a simple, low cost, highly efficient system of reclaiming high temperature sensible heat energy.
- The foregoing and other objects are achieved by this invention which provides a system for reclaiming heat, the system comprising a heat transfer arrangement for transferring heat from a high temperature exhaust gas of a gasifier to a working fluid, and thereby reclaiming high temperature sensible heat from the high temperature exhaust gas of the gasifier.
- The invention provides a method and system for converting high temperature heat energy into a useful product for processes such as electricity production, while minimizing the process carbon footprint.
- In an advantageous embodiment of the invention, the high temperature exhaust gas is characterized by a temperature of approximately between 250° C. and 2000° C.
- In one embodiment of the invention, the heat transfer arrangement is provided with a first duct having an inlet for receiving the high temperature exhaust gas, and an outlet for exhausting the high temperature exhaust gas at a reduced temperature. Additionally, a second duct has an inlet for receiving a heat transfer fluid and an outlet for exhausting the heat transfer fluid at an elevated temperature. A heat transfer arrangement conducts heat extracted from the product gas in the first duct to the heat transfer fluid in the second duct, thereby elevating the temperature of the heat transfer fluid. In a highly advantageous embodiment of the invention, the heat transfer fluid is steam.
- In a further advantageous embodiment of the invention, the heat transfer arrangement includes a heat pipe formed of a selectable combination of sodium, potassium, rubidium, and lithium. The heat pipe has a first end for communicating with the high temperature exhaust gas in the first duct, and a second end for communicating with the heat transfer fluid in the second duct. In respective embodiments, the heat pipe has an envelope formed of a selectable combination of stainless steel, Inconel, nickel, molybdenum, tungsten, niobium, carbon, carbon composite, and Hastelloy X.
- A safety valve ensures safe operation in some embodiments. In one embodiment, there is provided a heat transfer fin in the first duct for enhancing the transfer of heat from the high temperature exhaust gas to the heat pipe. Also, in other embodiments, an adiabatic zone is interposed between the first and second ducts.

fluid inlet 170 that receives spent steam or heat transferring fluid, and aheat energy outlet 150 that exhausts heated steam or heat transferring fluid. There is provided aheat transfer arrangement 135 that conducts heat extracted from the product gas in the first duct to the spent steam in the second duct, to form the heated steam. A specific illustrative embodiment of the invention oftransfer arrangement 135 will be described in detail below in relation toFIGS. 2 a and 2 b. - In one embodiment of the invention,
heat transfer arrangement 135 includes at least one sodium, potassium, rubidium, or lithium heat pipe or pipe that has a first end for communicating with the product gas in the first duct, and a second end for communicating with the spent steam in the second duct.

A safety valve ensures safe operation. - In some embodiments of the invention, a heat transfer fin is disposed in the first duct for enhancing the transfer of heat from the product gas to the heat pipe. Additionally, an adiabatic zone is in some embodiments of the invention interposed between the first and second ducts.
- In the practice of an illustrative embodiment of the invention,
product gas 125 exits gasifier 100, or a plasma reactor (not shown) in some embodiments, at approximately 1250° C. Approximately 27% of the total energy that is present inproduct gas 125 fromgasifier 110 is primarily in the form of sensible heat.
