steam boiler methanol city gas

Group R & D Center came to the exhibition hall, Mr. Liu Wei, president listened carefully throughout the various sectors, gathered to watch the exhibition hall to show a number of unique patented quick way of sound and light equipment, and careful inquiry of the current business development and marketing state. Also president of the company's current situation, the future direction of development, all kinds of high-end manufacturing equipment and remote monitoring system with unique features made a quick side centralized reporting.

20 tph WNS gas-fired fire tube boiler project for biotechnology industryA steam boiler methanol city 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.

Strict accordance with the operation of the gas steam boiler methanol city feed water softening process is provided gas steam boiler fouling not only reduces the thermal efficiency of the boiler, but also increases the temperature of the boiler heating surface, damage to the heating surface, even causing the boiler explosion. Thus, soft water treatment equipment, strict accordance with the operation of the boiler feed water softening processing apparatus, the control of boiler feed water quality, delay the formation of scale. At the same time, real-time control the size of the boiler, boiler scale control, cleaning the scale, if necessary, it is very important. Since the gas steam boiler and vapor - water heat temperature is higher than the temperature of the air system of the boiler room, part of heat to the surrounding air by radiation and convection, which became the heat loss. boiler. Accordingly, when the insulating layer and the heat pipe of the boiler system damage or leak is detected, it should be repaired, to reduce heat losses. Steam boiler burner gas noise increases, mainly because of lack of or close the valve in the oil passage into the oil, oil filter plugging; or into the oil due to the low temperature viscosity is too high or oil pump. Temperature is too high; oil pump failure; fan motor bearing damage; dirty because the turbine wheel, the device too loud. When said failure when using gas boiler, and since the viscosity of the oil is too high, atomization is not easy (heavy oil); and because the distance between the nozzle and the cyclone unsuitable; In addition, since the burner worn or dirty; also because reserve tank temperature is too high, leading to the oil pump steam; oil boiler or because the oil is hydrated. Gas steam boiler feed water containing various impurities and calcium and magnesium scale substances, boilers inevitably expanded. Very low thermal conductivity of the scale, once contaminated surface is the surface heat, the exhaust gas temperature of the boiler will increase, and due to the increase in thermal resistance, heat loss of the exhaust gas will increase. Experimental data show, 1mm scale formation in boiler heating surface, the heat loss of the exhaust gas will increase from about 2-4%. Scale thicker boiler heating surface, the greater the resistance, the lower the thermal efficiency of the boiler.

2. Oxygen corrosion

For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
