MIXED GAS FEEDER, CALORIFIC VALUE REGULATION APPARATUS, AND CALORIFIC VALUE REGULATION METHOD IN MIXED GAS FEEDER

摘要

PROBLEM TO BE SOLVED: To provide a mixed gas feeder preferable for stabilization of a calorific value of a fuel gas such as town gas, and its composition variation adjustment method.;SOLUTION: The fuel gas feeder 1 is provided with an LNG storage tank 5, a gasifier 3, an adsorption material filling column 2, and feeding lines L1-L3 for connecting these devices. In the LNG storage tank 5, LNG carried by a tanker or the like is stored. At a terminal end side of the feeding line L3, a loading apparatus (for example, gas engine) 6 is installed. Two different kinds of adsorption materials, i.e., the adsorption material 2a on a first layer at an entrance side and the adsorption material 2b on a second layer at an exit side are filled in the adsorption material filling column 2. The adsorption materials of the respective layers select the material having mutually different adsorption characteristic. For example, a charcoal raw material activated carbon and a palm shell raw material activated carbon can be selected.;COPYRIGHT: (C)2008,JPO&INPIT
