The application specifically relates to a preparation method of a low-gas-content silver plate, comprising the following steps: S1, adding silver powder into a crucible to smelt into a silver liquid; S2, adding a blocky silver graphite solid into the silver liquid, the blocky silver graphite solid is dispersed into silver graphite powder at high temperature, the smelting temperature is reduced and heating is performed; S3, pouring the silver liquid into a mold, and cooling to obtain the silver plate. The blocky silver graphite scrap is used as a deoxidizer to remove oxygen in the molten silver liquid, one is that when the blocky silver graphite is placed on the surface of the high-temperature silver liquid, the blocky silver graphite is broken into silver graphite powder and covers the surface of the molten silver liquid, the silver graphite powder is in full contact with the silver liquid and continuously consumes oxygen in the silver liquid; two is that no impurity ions are introduced, and the purity of the silver plate is maintained; three is that the broken silver graphite powder of the blocky silver graphite scrap, since the graphite powder is micron-level or even nanometer-level powder, air gas is difficult to penetrate the silver graphite powder layer and enter the molten silver liquid, and further plays a role of air isolation.

This utility model discloses a heating temperature control device for a biomass boiler deaerator, including a deaerator body. Two connectors are located on the right side of the deaerator body, and a three-way pipe is located on the right side of each connector. An adjusting component is located on the right side of the three-way pipe. A temperature sensor is installed at the upper end of the deaerator body, with its sensing end extending into the deaerator body. The adjusting component includes a rectangular box with an opening. Horizontal pipes are located on both sides of the opening. An adjusting block is slidably connected and sealed inside the rectangular box. An electromagnetic plate is located inside the rectangular box, and the adjacent sides of the electromagnetic plate and the adjusting block are elastically connected by springs. By incorporating a temperature sensor, adjusting component, and interlocking control with a controller, precise temperature control, effective prevention of feedwater pump cavitation, energy saving, and good sealing performance can be achieved.
