Method for waste heat recovery of steam generator
The previous technical process of steam generator waste heat recovery is very imprecise and not perfect. The waste heat in the steam generator depends on the blowdown process of the steam generator. The common recovery method generally uses a blowdown expander to collect the blowdown water, and then expands the capacity and depressurizes it to quickly form secondary steam, and then use the waste water generated by the secondary steam The heat does a good job of heating the water.
And there are three problems in this recycling method. First, the sewage discharged from the steam generator still has a lot of energy, which cannot be used reasonably; second, the combustion intensity of the gas steam generator is poor, and the starting pressure is poor. If the temperature of the condensed water is slightly higher, the water supply pump will be formed. Vaporization, can not operate normally; Third, in order to maintain stable production, a large amount of tap water and fuel must be invested. -

60kw Electric Steam Generator for bakery
When baking bread, the bakery can set the temperature based on the size and shape of the dough. Temperature is even more important for bread toasting. How do I keep the temperature of my bread oven within range? At this time, an electric heating steam generator is needed. The electric steam generator emits steam in 30 seconds, which can continuously control the temperature of the oven.
Steam can gelatinize the skin of bread dough. During gelatinization, the skin of the dough becomes elastic and tough. When the bread encounters cold air after baking, the skin will shrink, forming a crunchy texture.
After the bread dough is steamed, the surface humidity changes, which can prolong the drying time of the skin, keep the dough from deforming, prolong the expansion time of the dough, and the volume of the baked bread will increase and expand.
The temperature of water vapor is greater than 100°C, spraying on the surface of the dough can transfer heat to the dough.
Good bread making requires controlled steam introduction. The entire baking process does not use steam. Usually only in the first few minutes of the bake phase. The amount of steam is more or less, the time is long or short, and the temperature is high or low. Adjust according to the actual situation. Tengyang bread baking electric steam generator has fast gas production speed and high thermal efficiency. The power can be adjusted in four levels, and the power can be adjusted according to the demand of steam volume. It controls the amount of steam and temperature well, making it great for bread baking. -

The principle of electric heating steam generator
The working principle of the electric heating steam generator is: when the water supply system supplies water to the cylinder, when the water level rises to the working water level line, the electric heating element is powered on through the water level controller, and the electric heating element works. When the water level in the cylinder rises to a high water level, the water level controller controls the water supply system to stop supplying water to the cylinder. When the steam in the cylinder reaches the working pressure, the required pressure steam is obtained. When the steam pressure rises to the set value of the pressure relay, the pressure relay will act; cut off the power supply of the heating element, and the heating element will stop working. When the steam in the cylinder drops to the lower value set by the pressure relay, the pressure relay will act and the heating element will work again. In this way, an ideal, certain range of steam is obtained. When the water level in the cylinder drops to a low level due to evaporation, the machine can automatically cut off the power supply of the heating element to protect the heating element from being burned out. While cutting off the heating element power supply, the electric bell alarm sounds and the system stops working.
