  • Publication number: 20240353095
    Abstract: A gas-fired steam-injection boiler has a flue and a water supply pipeline. The flue is provided with a radiation section and a convection section. The water supply pipeline has, in the flue gas flow direction, a first pipe section located at an upstream portion of the convection section, a second pipe section is located at a downstream portion of the convection section, and a third pipe section arranged between the first pipe section and the second pipe section. In a water flow direction of the water supply pipeline, the second pipe section, the first pipe section and the third pipe section are arranged in sequence. By using a flue gas condenser, the temperature of flue gas can be further reduced, and the latent heat of vaporization of steam in the flue gas is absorbed to form condensate water.

  • Patent number: 10050460
    Abstract: This disclosure provides a mobile terminal, a DC-charging power source adaptor, and a charging method, where firstly the DC-charging power source adaptor is configured to communicate with the mobile terminal in a UART communication mode, and then a strategy to identity the type of charging is designed in the mobile terminal dependent upon configuration of communication pins of a different charging device, so that the mobile terminal identifies automatically the type of the external device. Also a specialized rapid charging mode is designed for the DC-charging power source adaptor, the battery of the mobile terminal being charged is DC-charged at large current by charging voltage output by the DC-charging power source adaptor, and the volt value of the charging voltage is adjusted dynamically according to the varying voltage of the battery.
