In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water low pollution boilers design chemical engineering to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
(2) Strictly control the low pollution boilers design chemical engineering water quality target. When the scale content in the water wall tube reaches 400mg/m, it should be pickled in time;
Hot water low pollution boilers design chemical engineering operating principle: the hot water boiler are performed simultaneously in two parts "pot" and "furnace", after the water into the boiler, soda system heat boiler heating surface will absorb transferred to the water, the water heated to a certain temperature and pressure generating hot water or steam, it is drawn applied. In the combustion apparatus part, continued burning of the fuel releases heat, high temperature flue gas produced by combustion heat propagation, heat transfer to the boiler heating surface, the temperature was gradually lowered itself, and finally discharged from the chimney.
With the rapid modernization of industry, the scope and quantity of boilers are increasing year by year, which makes the safety of boilers become an unavoidable topic, which is also a difficult problem that puzzles many enterprises. The safety measures of industrial boilers can protect the property and personal safety of our enterprises and individuals from damage. Here are some measures to prevent accidents of industrial boilers.
1. Observe the material, strength, type of connection, welding and cold-working components of the main pressurized parts of the industrial boiler drum, such as housing, head or tube plate, furnace liner, etc., to meet the design and manufacturing regulations. It is necessary to pay more attention to the fire tube boiler because of its larger diameter, more pressure components, more complicated connection types and so on.
2. During the maintenance of industrial boilers, the caustic soda brittleness, serious corrosion deformation and groove cracks should be highly vigilant, carefully checked, and the quality of maintenance must be guaranteed to prevent sudden tearing due to lack of strength or crack expansion.
3, operators must bear in mind: serious water shortage, do not feed water, so as not to overheat the wall of the pot, not as expected and brittle. Even high-quality and durable industrial boilers should be paid special attention.
4, industrial boiler safety valve and other safety accessories must always be sensitive, accurate and reliable. An important common cause of explosion in most small boilers is the absence of safety valves or failure of safety valves to cause overpressure. If the safety valve is normal and operated under low pressure, the explosion can be completely avoided.
5, pay attention to the links that are easy to be ignored. Cooking, bathing, heating, hot water boilers and tea stoves are also frequent accidents. These boilers are small in volume, low in pressure, more in the living department, often not noticed and paid attention to, it is easy to become a weak link and loophole in boiler safety management, so special attention should be paid to it.
