|---|
| 431036000 | Of or by burner feed supply heating structure | 7 |
| 20090274985 | POWDERED FUEL CONVERSION SYSTEMS AND METHODS - The burner preferably exclusively burns substantially explosible solid fuels and preferably has instant ON-OFF thermostat control, wastes no energy preheating the enclosure or external air supply, achieves stable combustion the moment the powder-air mix is ignited in our burner, is used in the upward vertical mode except for oil burner retrofits, burns a solid fuel in a single-phase regime as if it were a vaporized liquid or gas, is designed to complete combustion within the burner housing itself rather than in a large, high temperature furnace enclosure which it feeds, has an ultra-short residence time requirement, is a recycle consuming burner with self-contained management of initially unburned particles, is much smaller, simpler and lower cost, has a wider dynamic range/turndown ratio, is more efficient in combustion completeness and thermal efficiency, and operates with air-fuel mix approximately at the flame speed. | 11-05-2009 |
| 20130078583 | Heat Recycling System for a High-Temperature Exhaust Gas - A heat recycling system for a high-temperature exhaust gas contains a body having a combustion space, at least one burning device, and a storing device; characterized in that: the combustion space is connected with an exhaust pipe; the burning device is coupled with a heat recycling blower and a gas control valve; the storing device is secured on a distal end of the exhaust pipe and is comprised of a second control valve, a first store tank, and a second store tank; the second control valve is disposed on the exhaust pipe of the body and includes two output ends which connect with a gas guiding tube and a second guiding tube respectively; the first store tank is coupled with the gas guiding tube and is connected with a first check valve and a second check valve, the gas check valve is coupled with a first gas-exhausting blower. | 03-28-2013 |
| 431037000 | By controlling admittance of feed to structure | 4 |
| 20140242528 | Support system for radiant tube heaters - A modular support system for outdoor radiant tube heaters includes a frame defined by hollow beams for receiving fuel and electrical lines and supporting electrical heaters posts for supporting the beams and saddles for interconnecting the beams and mounting them on posts. | 08-28-2014 |
| 431038000 | By pressure of feed in structure | 3 |
| 20080268388 | Device for Controlling the Delivery of a Combustible Gas to a Burner Apparatus - A device for controlling the delivery of a combustible gas to a burner apparatus is provided. The device includes a main pipe for delivery of the gas in which are disposed first and second servovalves in cascade with each other, with respect to the direction of flow of the gas. The servovalves include respective valve seats associated with corresponding shut-off means with diaphragm control for the opening of the seats. The first and second servovalves include respective first and second control solenoid valves with electromagnetic operating means to control the opening/closing of the corresponding servovalve. The solenoid valves are arranged to act to open/close the pipes of respective servo-assisted control circuits, so as to control indirectly, by way of the diaphragm control, the respective shut-off means of the corresponding servovalve the pipes of the control circuit placing the main pipe in fluid communication with respective control chambers of the servovalves. | 10-30-2008 |
| 20130224670 | PREMIX GAS BURNER - An air/gas premix burner is disclosed. The air/gas premix burner includes a fan for sending an air/gas mixture towards a combustion head and a gas valve for regulating the introduction of combustible gas. The air/gas premix burner also includes an air/gas mixer, which comprises a localized pressure loss device, and a combustion head. The air/gas mixer includes two channels. One of the channels is provided with two hinged flaps that are designed to open and close for regulating the flow rate of the mixture. | 08-29-2013 |
| 20140030663 | SMART GAS BURNER SYSTEM FOR COOKING APPLIANCE - A cooking appliance having a gas burner operable to generate a quantity of heat is disclosed. The cooking appliance also includes a pressure sensor operable to measure the pressure of gas supplied to the gas burner from a gas valve. The gas valve is programmed to adjust the supply of gas to the gas burner based on the measured pressure of the gas. | 01-30-2014 |
| 431041000 | Supply of heat to heating structure controlled | 1 |
| 20130052595 | Indirect Fired Heater With Inline Fuel Heater - A heater and a method of its use are configured for use at cold operating temperatures. The heater has a supply line for transporting a volume of fuel between a fuel tank and burner. An inline heater is supplied in a supply line for the burner, and preferably is located upstream of a fuel filter for filtering the fuel so as to prevent wax condensation in the filter. The heater also has a return line that normally returns unused fuel from the burner to the heater, hence reducing the volume of fuel that needs to be heated by the heater and reducing system power requirements. The heater may be thermostatically controlled to maintain the temperature of the heated fuel to a value that is at or above a temperature required for good fuel atomization but below a flashpoint of the fuel. A valve is provided in the return line to permit diversion of the returned fuel to the fuel tank during a purge operation at initial startup. | 02-28-2013 |
