A quick-disconnect gas pipeline comprises a quick-disconnect device (QDD) which comprises a QDD male end and a QDD female end, and a gas hose. The QDD male end is connected to the gas pipeline inside the heating system and the QDD female end is connected to the gas hose outside the heating system. When the heating system is not used, it is easy to disconnect the QDD to prevent people from tripping over the long gas pipeline.

A method for providing a fuel includes providing a partially purified biogas at a first processing site, where the partially purified biogas is produced by multiple biogas sources and/or from multiple feedstock sources. The partially purified biogas is compressed, fed to a mobile tank, and transported by vehicle to a second processing site. At the second processing site, which may also receive biogas from a plurality of biogas sources, the partially purified biogas is further processed to produce a fuel or fuel intermediate.

A fuel combustion apparatus 2 according to the present invention includes: a combustion cylinder 4; a fuel feed unit 6 that introduces a swirling flow of an air-fuel mixture into the combustion cylinder; an ignition unit 10 including an igniter 32 located in the combustion cylinder 4; an ion detection unit 12 including a detector 40 located in the combustion cylinder 4; and a control unit 14 that adjusts a mixing ratio of the fuel based on a detection result obtained by the ion detection unit 12. Preferably, the fuel is ammonia. Preferably, the detector 40 is located in the vicinity of the igniter 32.

An all-purpose gas stove structure capable of increasing its air intake includes an all-purpose opening-covering case, an extended supporting frame, and at least one gas nozzle. The all-purpose opening-covering case includes an opening-covering case body for covering the heat source-receiving opening of a roasting/grilling device completely, and a gas controller with a gas operation unit for controlling the state of communication between gas input and output ends. The extended supporting frame is a box with a protective lid, is coupled to the inner side of the opening-covering case body at one end, and has a stove burner opening at the opposite end. The lateral walls of the protective lid are formed with vent holes. The gas nozzle is provided on the inner side of the stove burner opening. The all-purpose gas stove structure allows a ceramic roasting/grilling device to have a higher air intake and therefore produce higher heat.

This invention relates to portable heating systems that utilize a portable fuel source. Portable heating systems of the invention generally include a regulator that is configured to vaporize fuel released from a cartridge and to transfer the vaporized fuel to a burner for ignition.
