low nitrogen gas steam boiler
How to distinguish whether the steam generator is a low nitrogen steam generator
The steam generator is an environmentally friendly product that does not discharge waste gas, waste residue and wastewater during operation, and is also called an environmentally friendly boiler. Even so, nitrogen oxides will still be emitted during the operation of large gas-fired steam generators. In order to minimize industrial pollution, the state has promulgated strict nitrogen oxide emission indicators and called on all sectors of society to replace environmentally friendly boilers.
On the other hand, strict environmental protection policies have also encouraged steam generator manufacturers to continuously innovate in technology. Traditional coal boilers have gradually withdrawn from the historical stage. New electric heating steam generators, nitrogen low steam generators, and ultra-low nitrogen steam generators, Become the main force in the steam generator industry.
Low-nitrogen combustion steam generators refer to steam generators with low NOx emissions during fuel combustion. The NOx emission of the traditional natural gas steam generator is about 120~150mg/m3, while the normal NOx emission of the low nitrogen steam generator is about 30~80 mg/m2. Those with NOx emissions below 30 mg/m3 are usually called ultra-low nitrogen steam generators. -

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.
