    Abstract: A gas heater with specialized controls allows an operator to deploy a single device to heat and to dry when extracting moisture from a structure. The heater has a fan in a blow thru arrangement ahead of a burner. The burner uses either natural gas or liquefied petroleum gas. The heater has air flow, fan motor, temperature, and ignition controls and sensors. The heater delivers high temperature air to the structure that hastens evaporation as the heated air absorbs great concentrations of water vapor. Then the moisture laden heated air exits the building as the heater draws in fresh air, ducts it into a structure, and pressurizes the structure. This moisture laden air then leaks from the building through select windows using the energy imparted from the fan and then exhausts the moisture to the atmosphere, drying the structure.

  • Publication number: 20120000088
    Abstract: A clothes dryer may rely on a hybrid heat source for drying clothes. In some embodiments, the clothes dryer may rely on a combination of electrical energy to power the clothes dryer and hydronic heat to dry clothes. The hydronic heat may, for example, use hot water from an outdoor wood boiler circulated into a hydronic coil. Air passing over the hydronic coil may be warmed and delivered to the clothes dryer. The hybrid heat clothes dryer may reduce energy consumption from about 27 amperes to about 3 amperes.

  • Patent number: 8046932
    Abstract: A method and apparatus for operating a dryer used to reduce the moisture content of sheet material. A drying chamber is provided and includes a plurality of drying sections and a single point exhaust system. A seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the seal section are a combination of ambient air drawn through restricted passages at the entry to the seal section and exhaust gas that bleeds into the seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential. A heating system is also provided for heating the seal exhaust gases above the pitch condensation temperature for the flow.

    Abstract: A double pass reversing dryer provided with a main heat source for heating air passing through the upper plenum and a supplemental heat source for heating air as it passes from the upper plenum to the drying bin. When the double pass reversing dryer of the present invention is in an unbalanced state with more high moisture content agricultural material to be dried than low moisture content agricultural material to be dried, the temperature in the upper plenum is reduced and some of the air is vented directly to the lower plenum. The remainder of the air in the upper plenum is heated by a secondary heat source before the air passes into the drying bin containing the low moisture content agricultural material.

  • Patent number: 7975401
    Abstract: A clothes dryer has a degree of dryness control system that is responsive to moisture level of clothing articles tumbling in a drum and a target moisture value to control the drying cycle of the clothes dryer. The clothes dryer has a load size parameter producing module and an air flow detection parameter module. These modules generate one of two parameter conditions used by the processor to modify or select an appropriate moisture target value. The load size producing parameter module generates one of a small load input parameter and a large load input parameter. The air flow detection module produces one of a first and second air flow parameter to be utilized by the degree of dryness processor. As a result, the processor selects one of four target moisture values from these conditions.
