It is recommended to attach a sealed indirect resistance heating element, etc., attach a stainless steel tube 0 ring at the top, install an air extraction unit, cut the female thread, and use it tightly with a bolt-shaped lid. Primary coolant inlet nozzle, outlet nozzle, drain port, etc. are provided as appropriate, steam generator, primary coolant pump, pressurization The primary coolant circulation system will be constructed by installing equipment. A typical steam generator is shown in Fig. 4, but it is a vertical U-tube type and uses Inconel heat transfer tubes. The primary coolant enters through the lower inlet nozzle of the steam generator and flows out of the outlet nozzle through the heat transfer pipe.However, the water supply to the steam generator secondary side passes through the water supply ring from a position just above the upper end of the heat transfer pipe. After lowering the annular part around the heat transfer tube while mixing with the descending water separated by the steam separator, change the direction and move up the heat transfer tube, and the steam is removed from the upper steam separator. , And through a stainless steel pipe provided with a bypass control system, etc., through a dryer, etc., and through turbine power generation equipment such as speed control, etc., through a condenser, feed water circulation pump, feed water heater, etc. Construct the secondary water supply circulation system. Generally, steam extracted from the turbine is used as the heat source for the feed water heater, and the system configuration consists of a steam generator, a pressurizer, a turbine power generation unit, etc. May be used. :

In nuclear power, the primary coolant pump is a motor-driven centrifugal pump with a leak-controlled shaft seal, fitted with a flywheel at the top to slow down the flow during power outages.

However, during operation, the lower half forms a liquid phase and the upper half forms a gas phase, and surges caused by load fluctuations are controlled by controlling the evaporation and condensation of water by operating the electric heater and spray. It is designed to absorb.

For the main steam and reheat steam temperature control, etc., there is a spray method (superheat reduction method), which is a direct cooling method in which water or saturated steam is sprayed into the superheated steam. It is widely adopted and does not deny the rational use and application of facilities such as nuclear power generation and auxiliary equipment as appropriate.

Power is supplied to the multiple protected and sealed indirect resistance heating elements installed in indirect resistance heating furnaces such as the natural convection method, forced convection method, and pressurized type by the main control device such as an AC power supply. However, the active use of power is more reasonable than the rational use of external power and control systems, or self-active (including when configured as cross-compound power generation).

The playback shown in a), b) and c) in FIG. This does not mean that the rational use of feed water heaters, feed water heating tanks, etc. should be denied as appropriate. (The heat source of the feed water heaters, etc., uses turbine extraction, etc., and after work, leads to the condenser, It is common to collect water in the water supply system, and when multiple water tanks are installed, the installation of a water supply heating tank, etc., can be rationally omitted, and the use of a heat source such as a steam generator can be rationally used.

The general steam generator is shown in Fig. 4, but it is a vertical U-tube type and uses Inconel heat transfer tubes. The primary coolant enters from the lower inlet nozzle of the steam generator and flows out of the outlet nozzle through the heat transfer pipe.Water supply to the steam generator secondary side is through the water supply ring from a position just above the upper end of the heat transfer pipe. After lowering the annular part around the heat transfer tube while mixing with the descending water separated by the steam separator, the direction is changed and the heat transfer tube is raised. , And through a stainless steel pipe provided with a bypass control system, etc., through a dryer, etc., and through a turbine power generation facility, such as a speed control, etc., through a condenser, feed water circulation pump, feed water heater, etc. Construct secondary water supply circulation system.

When describing the relevant electric heating applications, etc., the selection of the electric capacity of the resistance furnace will be examined in consideration of factors such as the furnace type, the amount of heat treatment, and the heating temperature. In general, the heating element is selected appropriately according to the application, atmosphere, etc., and generally, in a furnace below 1,000 ° C, nichrome or Heating elements such as iron chromium (alloy heating elements) are used, and when the temperature is higher, use is made of, for example, silicon carbide or kanthal. In furnaces at 1,400 ° C or higher, molybdenum-gaiting heating elements are used. The furnace wall is made of refractory brick and heat insulating material, but sometimes it is lined with heat-resistant steel and used.

The materials used for the indirect resistance heating furnace (furnace wall) to be implemented should be made of low alloy steel, etc., and be made thicker so that the wall thickness is durable, and used by lining with heat-resistant stainless steel. The power supply of the resistance furnace is almost 200 V three-phase and 100 V single-phase.

The sealed heating element is made by insulating alloy heating elements and the like in a metal tube by insulating them with mica (mica). Insulating them with a space heater or powder of coal, alumina, magnesia, etc. and putting them in a metal tube. There is a single wire, power lot wire, aluminum power heater, etc., which have been put into practical use.

Direct resistance heating is internal heating, in which the object to be heated reaches the highest temperature. However, those with relatively high resistivity, such as water, are heated at a high voltage, and are practically used as electric boilers. Compared with the indirect type, it features higher heating efficiency, and it is configured using a heating element such as dichromium or iron chromium as the resistance core. It is advisable to insulate the inner wall with aluminum, magnesia, etc., and line it with heat-resistant stainless steel.
