natural gas steam boiler in power plant
Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler in power plant, and is responsible for subsequent transportation, installation and commissioning work .
20 tph WNS gas-fired fire tube boiler project for biotechnology industryA steam boiler in power plant 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.
Scale thermal conductivity gas steam boiler in power plant is only one out of steel gas steam boiler efficient and environmentally friendly use of non-corrosive cleaning agent in the cleaning process of cleaning the boiler. This will cause the device to the metal tube is exposed to the primary colors, and reduce the effects of biological fouling algae sludge. After ignition gas steam boiler, furnace and to observe the temperature of main steam. Main steam pressure rises, the boiler flue gas temperature significantly higher ignition. If the temperature does not rise, you should immediately to the scene to check the oil gun fire. Scale thermal conductivity gas steam boiler is only one-tenth of steel. When it is scale on the heated surface, which will hinder the heat transfer effect. To maintain the boiler output constant during use, the need to increase the temperature of the combustion side. Gas-fired steam boiler furnace exit temperature rise, increasing the loss of gas steam boiler scale on the device can effectively reduce the water wall heat transfer, the temperature of the water is likely to lead to an increase in the wall, resulting in a wall of water burst. When the gas steam boiler, the furnace will be a series of chemical and physical reactions. During use, it will be effective to form a dense and hard scale on the heating surface, which will lead directly to heat exchange. Due to the scale and efficiency while reducing corrosion can lead to heat gas boiler absorption.
If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired boilers is much more serious than coal-fired boilers, for two main reasons:
1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.
2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.
