That is to say, initial water supply process (now heating unit assembly 3 just started working and water in not boiling state) and water in fluidized state in the process with generation steam, when the water level in water-level control apparatus 4 detects container cavity 10 reaches setting height, controller 7 is controlled water pump 2 and is stopped supplying water to make the inflow of water inlet 11 as 0, when the water level in water-level control apparatus 4 detects container cavity 10 does not reach setting height, controller 7 control that water pump 2 continues or water supply start to make water inlet 11 there is a certain amount of inflow, thereby guarantee the height of water level in container cavity 10.
Below with reference to Fig. 1-Figure 11, describe according to the course of work of the steam generating system of the utility model preferred embodiment.
When needs steam generator 100 starts to produce steam, controller 7 is controlled water pump 2 to the interior water supply of container cavity 10, heating unit assembly 3 starts Fast Heating, the perisporium of exposed heating unit assembly 3 on the water surface of container cavity 10 starts to produce steam and is wrapped in steam, when the water in container cavity 10 comes to life, destroyed very soon the saturated vapor layer of heating unit assembly 3 periphery parcels and produced a large amount of steam, steam is derived by steam (vapor) outlet 12.When steam production is excessive or steam (vapor) outlet 12 is derived steam is smooth, the pressure in container cavity 10 can raise, and when steam pressure reaches predetermined value, pressure limiting device 5 is opened overvoltage steam (vapor) outlet 13, and the overvoltage steam in container cavity 10 is discharged by overvoltage steam (vapor) outlet 13.
In the process of generation steam, when the water seething with excitement is by the earth-continuity of water level control electrode 40 and heating unit assembly 3, the electric capacity 41 having charged is by the ground connection electric discharge of water level control electrode 40---water---heating unit assembly 3, now discharge loop is water level control electrode 40---water---heating unit assembly 3---the earth, there is low level with the connector place of electric capacity 41 in controller 7, controller 7 is controlled water pump 2 and stopped supplying water.Along with a large amount of evaporations of the water in the container cavity 10 of steam generator 100, when the water level liquid level of boiling is during lower than water level control electrode 40, now water level control electrode 40 contact with water, the discharge loop disconnection of electric capacity 41.Electric capacity 41 continues charging by the loop forming with the connector of controller 7, until electric capacity 41 chargings reach the connector high level voltage of controller 7, controller 7 is controlled water pump 2 and is started water supply, so height of water level in loop control steam generator 100, with the top that guarantees heating unit assembly 3 all the time above the exposed water surface in container cavity 10.
In the running of steam generator 100, when occur moisture in container cavity 10 very little, while occurring that dry combustion method or other situations make the temperature of heating unit assembly 3 reach certain value, controller 7 disconnecting external power supplys 400 are quit work heating unit assembly 3.
According to the steam generating system of the utility model embodiment, by being provided with the water-level control apparatus 4 for controlling the water level in container cavity 10, thereby the top that can guarantee heating unit assembly 3 is exposed above the water surface of container cavity 10 and guaranteed the height of water level in container cavity 10 all the time, make the steam production of steam generator 100 large and improved the speed of steaming, make the temperature stabilization of steam simultaneously, simultaneously by being provided with pressure limiting device 5, can avoid the hypertonia in container cavity 10 and cause security incident, again owing to being provided with protective device 6, can avoid heating unit assembly 3 because the situation that occurs dry combustion method is damaged, thereby can extend the service life of heating unit assembly 3, extended the service life of steam generating system and improved safety in utilization.
