101 psi gas fired steam boiler pressure
20 tph WNS gas-fired fire tube boiler project for biotechnology industryA 101 psi fired steam boiler pressure is one of the essential facilities of enterprises, which has a direct impact on the quality of the production line. YAN TAI HAI RUN SI BIOTECHNOLOGY Co., Ltd. specializes in manufacturing and wholesale of food and feed supplements as well as extension service of biotechnology. This company planned to expand business scope and invest 200 million yuan for the new production project of enzyme protein. As the country has been strengthening the comprehensive control of air pollution in industrial enterprises, and promoting the transformation construction of coal to gas and coal to electricity in recent years, the company decided to purchase one set of 20tph low NOx natural gas-fired steam boiler to response to the national call. With outstanding advantages of quality and service, ZOZEN won the favor of YAN TAI HAI RUN SI BIOTECHNOLOGY Co., Ltd.. ZOZEN provided the company with the WNS series gas-fired (oil-fired) boiler. This series gas-fired (oil-fired) boiler has wide fuel adaptability, which is applicable to a variety of fuels, including natural gas, coal gas, diesel and many other fuels. Furthermore, it adopts a large-diameter corrugated furnace and the high efficiency heat transfer element thread smoke tube to ensure the complete combustion of fuels; the thermal efficiency can reach above 98%. It is also equipped with an advanced low NOx burner imported from Europe to achieve the ultra-low NOx emissions. Both the product performance and exhaust emission entirely meet the actual requirements of the company.
Boiler steam temperature affect the safety and economy temperatures above will be lower than the rated temperature of the device, it will have a bad effect. If the temperature exceeds its rated value, the boiler will cause overheating of the relevant metal material, material creep acceleration, will shorten the life of the boiler. If the temperature is too high, but some of the key components of the boiler would cause damage, can also cause serious and even superheater tube rupture. If the temperature is lower than the rated temperature, vapor enthalpy is reduced, increased air consumption, decreased economy. This will reduce the thermodynamic cycle efficiency of the plant, the steam humidity at the last stage blades of the gas turbine increases, causing erosion and damage to water droplets gas turbine blades, affect the safe operation of the gas turbine. Ruoyin with water vapor causes a decrease in temperature, the moisture in the salt impurities formed in the superheater scale, pipe valves, gas turbine blade, because the superheater lead to reduced heat transfer, the temperature decreased, damage increased wall temperature; and cause the valve plug, the operation failure; and a gas turbine blade erosion, loss of balance and vibration occurs. Temperature fluctuations reason superheater actual heat transfer the vapor does not reach the required amount of heat absorbed corresponding balancing. When the heat absorbed is greater than the heat transfer, the temperature rise; conversely decreased. Many factors affect the temperature change, including both gas side and the vapor side. Such as boiler load increased, but also to ensure the boiler load unchanged or decreased in order to prevent pressure shall increase the amount of fuel and air supply, strengthen the burning, causing the furnace exit flue gas temperature of the flue gas volume increases and lower water temperature , temperature increase; If the oil and gas fuel is combusted in the furnace carbon black is not fully formed, into the superheater flue causing secondary combustion, but also greatly increase the superheat temperature. Reducing the temperature of the main reasons: improper adjustment of combustion, low flame center furnace; superheater area is small, or too much leakage at the furnace wall; Save water flow rising or temperature reduction; drum water level or high gas-water separator separating efficiency is lowered, the humidity of the vapor is increased; superheater tube fouling, reduced heat absorption and the like.
Shandong Mining Group in the six months after the boiler use, users submit a report to our company, our company started in 2017 using WDR0.5-0.8-Ⅱ electric fast Boiler Co., Ltd. of heating 101 psi fired steam boiler pressure. Large output, stable and reliable, high degree of automation, simple operation, do especially in terms of security is in place. After-sales service is very timely response to our technical consulting reply quickly and accurately. Whether it is party party products or fast fast service. My company is very satisfied. --customer feedback
Process safety valve check valve gas 101 psi fired steam boiler pressure is one of the three safety accessories gas steam boiler, when the boiler pressure is too high, the pressure relief valve will automatically exhaust, gas steam boiler is the important safety equipment . The case of a new installation, overhaul, lack of consumer safety valve shutdown and restart more than three consecutive months, have had to re-check safety valve, safety valve to ensure accurate and reliable by the company safety officer, boiler technician, run operators, maintenance personnel together with the completion of the adjustment. Valve adjustment procedure is as follows: 1, the steam boiler when the gas vapor pressure close to the operating pressure of the safety valve, and retest check valve to the air motor exhaust, drainage accident flexibility and reliability of the electric valve, and the panel reinspection situ pressure gauge, the water level of accuracy, such as failure, not allowed to heat the school. 2, ready to call and check the quality of communication tools, a signal indicating whether the good. 3, adjust the safety valves, boiler pressure should be kept stable, pay attention to monitoring gas steam boiler drum level, and maintain normal. 4, steam boiler safety valve to adjust the pressure gauge in place of instructions shall prevail. If necessary using 0.4 or more for the accuracy of the gauge. 5, adjust the safety valve should be carried out only by descending. It should checksum gas steam boiler tuning high pressure safety valve, after the school seizure of the entire set of low pressure relief valve. 6, the following should be in the 0.3MPa, the movement preventing measures must do a good job of setting relatively low pressure steam boiler safety valve safety valve before adjusting. 7, by combustion, and exhaust steam adjust the degree of opening to the air slowly and smoothly up to the required setting pressure. 8, when the gas pressure steam boiler safety valve set pressure to rise if action is normal, then the action and reseating pressure values recorded. If action is not correct or not action should be immediately opened to the air exhaust valve, while the combustion boiler weakened, stop boost, and buck 0.3MPa or less, re-adjust the boiler technician as required by maintenance personnel, until the compliance date. (Lead or lag 0.05MPa action is normal). 9, after the completion valve to adjust gas steam boiler, boiler 0.3MPa or less down to the lifting device and can be installed and fastened to the protective cover, a braking measure required under check valve removal, then Articles 7, 8 verify until all required safety valve calibration check is completed. 10, the safety valve to adjust the gas boiler, check the results recorded in the "safety valve to adjust the recording Visa" within the participants should verify the signatures and Internet safety valve input to the corresponding data in the ledger. During operation gas steam boiler, not only to regularly check on the safety valve, at the same time, we must regularly monitor boiler inspection to ensure that the boiler fully meet the safety requirements!
