The influence of steam generator outlet gas flow rate on temperature!
The influencing factors of the temperature change of the superheated steam of the steam generator mainly include the change of the temperature and flow rate of the flue gas, the temperature and flow rate of the saturated steam, and the temperature of the desuperheating water.
1. The influence of flue gas temperature and flow velocity at the furnace outlet of the steam generator: when the flue gas temperature and flow velocity increase, the convective heat transfer of the superheater will increase, so the heat absorption of the superheater will increase, so the steam The temperature will rise.
There are many reasons that affect the flue gas temperature and flow rate, such as the adjustment of the amount of fuel in the furnace, the strength of combustion, the change of the nature of the fuel itself (that is, the change of the percentage of various components contained in coal), and the adjustment of excess air. , the change of burner operation mode, the temperature of the steam generator inlet water, the cleanliness of the heating surface and other factors, as long as any one of these factors changes significantly, various chain reactions will occur, and the It is directly related to the change of flue gas temperature and flow rate.
2. The influence of the saturated steam temperature and flow rate at the superheater inlet of the steam generator: when the saturated steam temperature is low and the steam flow rate becomes larger, the superheater is required to bring more heat. Under such circumstances, it will inevitably cause changes in the working temperature of the superheater, so it directly affects the temperature of the superheated steam. -

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. -

How to judge whether the steam boiler is energy-saving
For the majority of users and friends, it is very important to purchase a boiler that can save energy and reduce emissions when purchasing a boiler, which is related to the cost and cost performance of the subsequent use of the boiler. So how do you see whether the boiler is an energy-saving type when purchasing a boiler? Nobeth has summarized the following aspects to help you make better boiler selection.
1. When designing the boiler, the reasonable selection of equipment should be carried out first. In order to ensure that the safety and energy saving of industrial boilers meet the requirements of users, it is necessary to choose the appropriate boiler according to the local conditions, and design the boiler type according to the scientific and reasonable selection principle.
2. When selecting the type of boiler, the fuel of the boiler should also be correctly selected. The type of fuel should be reasonably selected according to the type, industry, and installation area of the boiler. Reasonable coal blending, so that the moisture, ash, volatile matter, particle size, etc. of the coal meet the requirements of imported boiler combustion equipment. At the same time, encourage the use of new energy sources such as straw briquettes as alternative fuels or blended fuels.
3. When selecting fans and water pumps, it is necessary to choose new high-efficiency and energy-saving products, and not to choose outdated products; match the water pumps, fans and motors according to the operating conditions of the boiler to avoid the phenomenon of “big horses and small carts”. Auxiliary machines with low efficiency and high energy consumption should be modified or replaced with high-efficiency and energy-saving products.
4. Boilers generally have the highest efficiency when the rated load is 80% to 90%. As the load decreases, the efficiency will also decrease. Generally, it is sufficient to select a boiler whose capacity is 10% larger than the actual steam consumption. If the selected parameters are not correct, according to the series standards, a boiler with a higher parameter can be selected. The selection of boiler auxiliary equipment should also refer to the above principles to avoid “big horses and small carts”.
5. To reasonably determine the number of boilers, in principle, the normal inspection and shutdown of the boilers should be considered.
