A catalytic tank heater includes a removably attached catalytic heater cartridge having catalytic material. The heater is attached to an LPG tank to position the catalytic heater cartridge to face the tank. The catalytic heater cartridge covers a plenum chamber of the catalytic tank heater. A fuel distribution header and heating element are positioned within the plenum chamber and are controlled to initiate combustion of the catalytic material to heat the tank. Vapor from the tank is provided as fuel to the catalytic tank heater, and is regulated to increase heat output as tank pressure drops. The catalytic heater cartridge can be replaced with a new cartridge while at the location of the tank on a property.

The invention relates to a start-up system (1) for a catalytic burner, the start- up system (1) comprises a start-up system housing (22) that defines a flow channel for fuel to be combusted. An electrical conductor(11) coated with a catalyst extends across the flow channel and is provided with electrical connections (12, 13) at either side of the flow channel. The electrical conductor (11) has a cross-section that is smaller at the centre of the flow channel than it is at either side of the flow channel. The invention also relates to a method of starting-up a catalytic burner.
Abstract:
The present invention concerns a method with associated equipment for feeding two gases into and out of a multi-channel monolithic structure. The two gases will normally be two gases with different chemical and/or physical properties. The gases, here called gas 1 and gas 2, are fed by means of a manifold head into channels for gas 1 and gas 2 respectively. Gas 1 and gas 2 are distributed in the monolith in such a way that at least one of the channel walls is a shared or joint wall for gas 1 and gas 2. The walls that are joint walls for the two gases will then constitute a contact area between the two gases that is available for mass and/or heat exchange. This means that the gases must be fed into channels that are spread over the entire cross-sectional area of the monolith. The present invention makes it possible to utilise the entire contact area or all of the monolith's channel walls directly for heat and/or mass transfer between gas 1 and gas 2. This means that the channel for one gas will always have the other gas on the other side of its channel walls, i.e. all adjacent or neighbouring channels for gas 1 contain gas 2 and vice versa. The present invention will be particularly applicable for making compact ceramic membrane structures and/or heat exchanger structures that must handle gases at high temperature. Typical applications are oxygen-conducting ceramic membranes, heat exchangers for gas turbines and heat exchanger reformers for production of synthetic gas.
