The invention relates to a package material horizontal casting shaping device. Wherein, it comprises core metal temperature-control pot, package metal temperature-control pot, core metal liquid irrigate tube, package metal crystallizer, drawing device, temperature tester, heating element and secondary cooler; and the producing method comprises the temperature of package metal is kept by the package metal temperature-control pot, passing through the package metal thermal-insulated chamber, irrigates into the casting mould formed by crystallizer and irrigate tube to be solidified into package metal tube; the core metal is solidified in the solidified package metal tube, with he package metal tube to form composite cast ingot; the cast ingot via second cooler is cooled and drawn by the drawing device, to be cut by cutter at certain length. The invention has simple process and lower cost, while the interface between package metal and core metal has non oxidization and non pollution.

The invention discloses a device for matter heat separation of a solid fuel and fused salt integrated boiler. The device is mainly composed of an expansion groove, fused salt grooves, fused salt guide pipes, an insulating layer, a burning cavity, an air preheating recoverer, an air blower, another air blower, a centrifugal fan, circulation burning pipes, a waste heat recovery water tank, a combustion air cavity, a fuel preheating coil pipe, a high pressure plunger pump, a steam coil pipe, a steam header, a steam generator main body, a high pressure spraying device, a desulfurization and denitrification device, a dedusting lime water pool, a spraying head, a circulation water pump, an induced draft fan, a chimney, a solid matter conveyor, a liquid matter conveyor, a matter decomposing coil pipe, a cyclone separation tower, a decomposing reduction chamber and a cooling tower. The device has the beneficial effects that fused salt of a fused salt constant temperature system is directly heated in a hearth, and the steam pipe temperature and the heat decomposing pipe temperature are controlled by heat of the fused salt; jet fog enters a steam pipe to obtain steam; and materials enter a heat decomposing pipe to conduct matter decomposing. The device further has the beneficial effects that a steam decomposing and separating technology is adopted for replacing an existing decomposing and separating technology, and the problems of complex technological processes, equipment and the like are solved.

The invention relates to a plastic inner liner of a water heater, comprising a liner body provided with a cold water inlet and a hot water outlet. The invention is characterized in that the liner body comprises a plurality of parallel horizontal pipes and a plurality of parallel longitudinal pipes; and the horizontal pipes and the longitudinal pipes are positioned on the same plane and are connected with each other by interpenetration. The plastic inner liner of the water heater adopts pipe network type plate structure, has strong pressure bearing capacity, secure structure and good water mobility, can be manufactured by plastic materials, does not produce scale, resists corrosion, occupies less space and is convenient to design and install.

The invention discloses an infrared radiation ceramic heater, which comprises a quartz outer tube and a quartz inner tube. A silicon carbide rod is installed in the cavity, and the diameter of the through hole set in the middle of the quartz inner tube is equal to and greater than or equal to the length of the quartz outer tube. Silicon pad. The invention is mainly used for medium heating of heaters, and can also be used for heating in industrial production, especially for heaters using water circulation. The product of the invention can directly heat the water, so that the temperature of the water rises quickly. The water absorbs heat through the quartz outer tube and the quartz inner tube, and the thermal efficiency is high. Because the infrared radiation rate is greater than 97%, the energy consumption is low, which is better than that of the existing carbon fiber filament heating. , Electric heating tube heating energy saving 38-45%. Another great advantage of the present invention is that the service life is long, and the shortcoming that electric heating and carbon fiber heating are prone to failures is completely avoided.

The present invention relates to a fuel saving gas welding apparatus that comprises: an oxygen gas supply unit that supplies an oxygen gas to a welding torch (3); a fuel gas supply unit that supplies a fuel gas to the welding torch (3); an ignition gas supply unit that supplies flame required for the ignition of the welding torch (3); and a control means (2) that discharges the fuel gas with a delay of 0.2 to 1 second after the oxygen gas to prevent reverse flow and flash back, wherein the fuel gas (e.g., acetylene gas) is supplied with a delay of 0.2 to 1 second after the oxygen gas by using a delay timer (T), a relay (Ry), a switch (12), and solenoid valves (S1) (S2), which makes it possible to prevent reverse flow and flash back in the welding torch (3), to significantly reduce the fuel gas by 30% or more, and to enhance the productivity by 30% or more.
