What to do if the steam generator is overpressured
The high-pressure steam generator is a heat replacement device that reaches steam or hot water with a higher output temperature than under normal pressure through a high-pressure device. The advantages of high-quality high-pressure steam generators, such as complex structure, temperature, continuous operation, and appropriate and reasonable circulating water system, are widely used in all walks of life. However, users will still have many faults after using the high-pressure steam generator, and it is particularly important to master the method of eliminating such faults. -

Steam Boiler Blowdown Method
There are two main blowdown methods of steam boilers, namely bottom blowdown and continuous blowdown. The way of sewage discharge, the purpose of sewage discharge and the installation orientation of the two are different, and generally they cannot replace each other.
Bottom blowdown, also known as timed blowdown, is to open the large-diameter valve at the bottom of the boiler for a few seconds to blow down, so that a large amount of pot water and sediment can be flushed out under the action of boiler pressure. . This method is an ideal slagging method, which can be divided into manual control and automatic control.
Continuous blowdown is also called surface blowdown. Generally, a valve is set on the side of the boiler, and the amount of sewage is controlled by controlling the opening of the valve, thereby controlling the concentration of TDS in the water-soluble solids of the boiler.
There are many ways to control boiler blowdown, but the first thing that must be considered is our exact goal. One is to control traffic. Once we have calculated the blowdown required for the boiler, we must provide a means of controlling the flow. -

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. -
