Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler instant equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
A correct steam boiler instant shutdown: 1, the steam boiler is not used to determine, fireman and support staff to coordinate Division, before proceeding shutdown operation. 2, to reduce fuel (coal), and then reducing the amount of wind, until after the load falls to zero, closing the main valve and stop the air blowing, the wind is stopped after 5 minutes. 3, the shutter closing the flue, each door seal, manholes. 4, the boiler flame, when the vapor pressure exceeds the working pressure, exhaust valves should be opened or add water to the boiler and the blowdown, but should not significantly cooled boiler. 5, boiler pressure is not reduced to zero, to maintain the normal water level, the operator may not leave their posts until the pressure to zero, then make sure all links are correct before they show proper steam boiler shutdown.
The boiler pressure usually referred to in the boiler industry means the force perpendicular to the unit wall area of the vessel, generally expressed as "Mpa", and can also be expressed in terms of "psi", "bar", "kgf/c㎡" and "atm". A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. When water is boiled into steam its volume increases about 1,600 times, producing a force that is almost as explosive as gunpowder. This causes the boiler to be extremely dangerous equipment that must be treated with utmost care.
Conventional low nitrogen low nitrogen gas boiler instant combustion technology mainly focus on how to reduce the combustion temperature to reduce the thermal nitrogen oxides (NOx) generated carried out, the main techniques include staged combustion, premixed combustion, flue gas recirculation. 1, a fuel staged combustion / combustion air staging thermal NOx amount largely depends on the level of the combustion temperature. In the equivalent ratio of the combustion temperature reached the highest value in the case 1, the combustion under lean or rich combustion cases, the combustion temperature will fall much. Using this principle to launch a staged combustion technology.
