Aforesaid system and method promotes to reduce the entire length and/or the diameter of syngas cooler when keeping steam to produce and reducing the cost of the size that depends on syngas cooler.Particularly, at run duration, synthetic air is discharged the top of the syngas cooler that enters vertical orientation from gasifier.This synthesis gas flows along hot plate then, passes the feedwater of the boiler of hot plate to add heat flow, thereby produces steam.In essence because limited pathways for vision, flow through the synthesis gas of syngas cooler since particulate matter and optically dense, particulate matter has limited the radiant heat that is transmitted to hot plate.In addition, the particulate matter in the synthetic air also can be deposited on the hot plate, further reduces and conducts heat.
Therefore, disclosed in this article hot plate is oriented vertical pattern, and separates from the center line of syngas cooler, to promote to prevent the accumulation from the solid of synthetic air.In addition, compare with known syngas cooler, described in this article hot plate is configured to promote to provide the bigger exposure of the stream of hot plate surface area to syngas cooler.Particularly, described in this article hot plate is constructed with geometric configuration, and wherein the quantity of hot plate, angle and length are different with known syngas cooler hot plate.More specifically, hot plate is constructed with different length and/or nonlinear geometry and/or is configured to and is connected on the pipe cage with the angle that the wall with respect to syngas cooler tilts.
By accumulation that reduces solid and the surface area that increases hot plate, disclosed in this article hot plate promotes to increase the heat transfer from the synthetic air to the boiler feedwater, thereby increases steam production.In addition, described in this article hot plate need to be configured to less space in syngas cooler.Therefore, hot plate promotes to reduce the entire length and/or the diameter of syngas cooler when keeping the steam generation and reducing the cost of the size that depends on syngas cooler.
As using in this article, with the odd number narration and the front have speech " " or " one 's " element or step and be not construed as a plurality of described elements or step are foreclosed, unless such eliminating is pointed out clearly.In addition, be not to be intended to be interpreted into the existence that yet to comprise the other embodiment of described feature foreclose to mentioning of " embodiment " of the present invention.
More than described the exemplary embodiment of the system and method that is used to make the syngas cooler hot plate in detail.Illustrated system and method is not limited to described in this article specific embodiment, and is on the contrary, can be with other member as herein described independent and utilize the member of system dividually.In addition, can be with described other step herein independent and utilize the step of in method, describing dividually.
Though described the present invention, will recognize that the remodeling in the available spirit and scope that are in claims is put into practice the present invention according to various specific embodiments.
