Abstract: The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls.

Accordingly, the method and the apparatus can diminish a difference between drying rates in on one end side and in the other end side of the long support, in the whole drying zone. Thus, the method and the apparatus can uniformly dry the support and inhibit the production of a dry spot.

Abstract: The invention relates to a method for drying a fibre-based pulp web (2), and to a drying box (1) used in the method. According to the invention, the drying box (1) contains drying zones (9a-9e), to each one of which hot drying air can be blown independently so that the web can be dried in the various zones at different temperatures. The temperature of the first zone (9a) can thus be lower than that of one or more subsequent zones (9b-9e) to prevent the water in the incoming wet web from boiling. The last zone in the drying box (1) can be a separate cooling zone (11), wherein the web is cooled by indoor air from outside the box. The temperatures can be adjusted by adjusting, with the aid of valves (8), the pressure of the steam, which heats the drying air that is fed into the various zones (9a-9e), on the basis of the temperatures measured by the sensors (23) for the various zones and of the basis weight and moisture measurements carried out on the web (2) that goes into the box (1) and comes out of the box.

Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.
