External Gas Heating Device of Coal Pyrolyzing Furnace

Abstract: An external gas heating device of a coal pyrolyzing furnace is positioned on the middle part of a furnace body and around the outer wall of a carbonizing chamber and comprises more than one group of first gas heater and second gas heater that have the same structure and a gas reversing device. The gas reversing device supplies air and purified gas into a combustion chamber of the first gas heater to be combusted and meanwhile sucks hot waste gas from a combustion chamber of the second gas heater. In the same way, the gas reversing device supplies air and purified gas into the combustion chamber of the second gas heater to be combusted and meanwhile sucks hot waste gas from the combustion chamber of the first gas heater. In the present invention, the aims of energy conservation and consumption reduction are fulfilled, and the coking cost is saved.

Gas leak detection device

Abstract: The utility model discloses a gas leak detection device, including host system and the inlet channel who connects in order, main entrance solenoid valve and be used for the external air outlet channelwho is surveyed the pipeline, the intercommunication has bypass passage and has the differential pressure sensor who is used for atmospheric pressure pressure differential to detect through other pipe connection between inlet channel and the air outlet channel, bypass passage is equipped with the capillary hole so that limiting flow in being capillary or bypass passage, main entrance electromagnetic valve control signal input, differential pressure sensor detect signal output part respectively with the host system electricity is connected. This device is convenient for connect at the air supply and is surveyed and carry out gas leak detection between the pipeline, if establish ties on the gas pipeline of gas heater gas -cooker, it uses conveniently.

Method for keeping cooked rice hot and rice cooker

Abstract: PROBLEM TO BE SOLVED: To keep delicious cooked rice ready at all times for a long time by keeping cooked rice hot by a heat reserving heater after the rice is cooked and reheating the cooked rice by actuating a gas heater, under respective temperature conditions. SOLUTION: After a rice cooking operation is finished, a heat reserving operation is started. In the heat reserving operation, the inside of a rice cooking pot 2 is kept at about 70 deg. by intermittently supplying power to an electric heater 7 based on the temperature of a bottom part of the rice cooking pot 2 detected by a temperature sensor 8. At the same time, a timer is actuated. Monitoring the timer, it is judged whether seven hours have been passed since the heat reserving operation is started, When seven hours are passed, a gas heater 5 is actuated to rapidly raise the temperature of the rice cooking pot 2. The heating time is set according to a quantity of rice detected by the rice cooking operation, The rice cooking pot 2 is heated by the gas heater 5, for example, for three min. when the quantity of rice is large. As a result, the temperature of the cooked rice in the rice cooking pot 2 is raised to 80 to 110 deg.C. Accordingly, the number of thermophilic bacillus generated during the rice cooking operation is decreased.
