A fuelgas range is provided with multiple burners and control apparatus which assures flow of an ideal pre-mixture of fuelgas and air to each burner over a wide range of flow values and independently of each other burner. The control apparatus includes an air blower, an air plenum, and valve means for introducing air to the range burners from the plenum and maintaining the pressure of air in the plenum at a constant value.

A grain drying system includes a fluidized bed for burning grain dust. The hot gases produced by the combustion of the grain dust are directed to a cyclone for cleaning and then to a known grain dryer. The ashes or other particles removed from the hot gases by the cyclone are returned to the fluidized bed.

An efficient solar collector that uses a collector panel formed of strips similar to conventional aluminum siding includes air distribution channels along opposite edges of the collector panel. These air distribution channels are formed of enlarged collector panel strips and form headers. Openings are formed through the wall on which the siding is mounted adjacent each of these channels so air from the interior of the building may flow through one or more lower openings into one of the channels, then through the space between the exterior side of the wall and the panel into the other channel, and through the other openings to return to the interior of the building. The air is heated indirectly by the solar radiation impinging on the collector panel as the air flows through the space between the wall and the panel. To increase the efficiency of the collector, a blower can be installed in one of the openings to increase the air flow through the collector.

Passive environmental heating and cooling systems are described, which utilize heat pipes to transmit heat to or from a thermal reservoir. In a solar heating system, a heat pipe is utilized to carry heat from a solar heat absorber plate that receives sunlight, through a thermal insulation barrier, to a heat storage wall, with the outer end of the pipe which is in contact with the solar absorber being lower than the inner end. The inclining of the heat pipe assures that the portion of working fluid, such as Freon, which is in a liquid phase will fall by gravity to the outer end of the pipe, thereby assuring diode action that prevents the reverse transfer of heat from the reservoir to the outside on cool nights. In a cooling system, the outer end of the pipe which connects to a heat dissipator, is higher than the inner end that is coupled to a cold reservoir, to allow heat transfer only out of the reservoir to the heat dissipator, and not in the reverse direction.
