Commissioning and operation of steam boiler for mechanical engineering with price replenishment operations: steam boiler, which runs before commissioning, should be carried out and how to specific operations? Their pay, generally are there? And, associated with steam boiler problems, what are we do not know? These questions are all about this kind of boiler steam boiler, so the following to learn and understand, to grasp, so that flexibility in the use in practice. 1. steam boiler, which runs before commissioning, should be how to operate and carry out specific? Steam boiler, which runs before commissioning work on specific steps and content, mainly as follows: Step a: open the inlet valve, while closing the steam outlet valve, and starts the feed pump, injecting water into the boiler. It should be noted that the use of demineralized water. When the water level rises to the low water level of the gauge, check whether it is stable, whether the decline phenomenon. Step two: steam heating boiler ignition, and in its initial stage should be slow, the speed is not too fast. Generally, the pressure is increased from an initial value to the time spent working pressure, it should be 3-4 hours. At the same time, but also on the water level to wash. For pressure gauge, check whether the display is normal, and into the hole at the boiler leaks and other issues.
What is the operating principle of the gas boiler: With the national energy saving policies have been introduced, the traditional coal-fired industrial boilers gradually being replaced by gas-fired boiler, industrial power about a revolution in the field of energy saving and environmental protection are taking place. Many users of gas-fired boilers there are a lot of places do not understand, fast Boiler simple for everyone to explain some principles of operations on the gas boiler. 1, injected into the boiler furnace combustion head-mixed fuel and air, the combustion by the ignition device in the head of the full ignition gas furnace, a heating furnace to achieve a boiler, furnace tube effect. Generally begins, a good boiler, the combustion chamber can design a large capacity multi-curve, so that the heating area and stroke to increase the fuel in the furnace body, which can improve the thermal efficiency. Thus, the key gas-fired boiler combustion head, so that the air mixed gas and, after reaching a certain percentage in order to better enable complete combustion of fuel.
In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boiler nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boiler for mechanical engineering with prices for low-nitrogen emissions transformation.
