Abstract
A bustle for use on a flare or an exhaust stack of, for example, a landfill gas treatment system, efficiently transfers gas from the stack to a waste heat recovery system associated with the landfill gas treatment system without substantially affecting the operation of the landfill gas treatment process. The bustle enables the heat recovery system to recover at least a portion of the energy within the exhaust produced by the gas treatment system and to provide the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process.
Claims38
A stack bustle for use in a gas exhaust system having an exhaust stack, the stack bustle comprising:
- a circumferential piping section co-extensive with the exhaust stack, the circumferential piping section including a first wall and a second wall;
- an orifice disposed within the first wall of the circumferential piping section or in the exhaust stack, the orifice adapted to be connected to a gas transfer pipe for transferring gas from the circumferential piping section;
- and
- a plurality of slots disposed within the second wall of the circumferential piping section or within the exhaust stack, the plurality of slots forming a fluid passageway between the exhaust stack and the circumferential piping section, the plurality of slots being circumferentially disposed around the circumferential piping section or the exhaust stack,
- wherein an area profile of the plurality of slots differs at different circumferential locations of the circumferential piping section or exhaust stack.
A stack bustle for use in a gas exhaust system having an exhaust stack, the stack bustle comprising:
- a circumferential piping section disposed within or adjacent to the exhaust stack, the circumferential piping section including a first wall and a second wall which form opposite sides of the circumferential piping section;
- an orifice disposed within the circumferential piping section, the orifice adapted to be connected to a gas transfer pipe for transferring gas from the circumferential piping section;
- and
- a slot disposed within the second wall of the circumferential piping section, the slot forming a fluid passageway between the exhaust stack and the circumferential piping section, said slot circumferentially disposed around the circumferential piping section,
- wherein the distance between the first wall and the second wall forming the immediately opposing sides of the circumferential piping section varies around the circumference of the exhaust stack.
A stack bustle for conducting exhaust gases from a stack, comprising:
- a gas transportation corridor having a first wall and a second wall;
- an exhaust gas inlet disposed in the first wall of the gas transportation corridor and adapted to cooperate with the stack to allow gas within the stack to enter the gas transportation corridor at multiple spaced-apart locations in the gas transportation corridor;
- and
- an orifice disposed in the gas transportation corridor to enable gas to exit the gas transportation corridor;
- wherein an area profile of the exhaust gas inlet differs along the gas transportation corridor.
A stack bustle for conducting exhaust gases from a stack, comprising:
- a gas transportation corridor having first and second opposite walls;
- an exhaust gas inlet disposed in the gas transportation corridor and adapted to cooperate with the stack to allow gas within the stack to enter the gas transportation corridor at multiple positions within the gas transportation corridor;
- and
- an orifice disposed in the gas transportation corridor to enable gas to exit the gas transportation corridor;
- wherein a cross-sectional area of the gas transportation corridor varies along the gas transportation corridor.
