Provided is a method of amplification of coke oven gas through reacting high-temperature carbon with carbon dioxide andor water using waste heat generated in a coke oven. The apparatus also includes a liquid collecting system that includes a liquid collection member having a permeable member through which a liquid is collected from a surface of an object opposite to the liquid collection member, wherein the permeable member has a plurality of passages that generate a capillary force. The system of the invention utilizes multiple parallel data channels that are coordinated by a single reservation channel.
