What safety matters should be noticed in the operation of industrial boilers?

Industrial boiler is a kind of equipment which must be used by many manufacturing enterprises. It can provide sufficient thermal energy for the production of enterprises so as to ensure that the production can be carried out in an orderly manner. However, because the industrial boiler is dangerous when it is used, the workers who operate it must pay attention to the following items in their daily work in order to better prevent the occurrence of safety accidents. So what safety matters should be noticed in the operation of industrial boilers?

1. Industrial boilers should check the inlet and outlet valves of their gas meters and the main valves in front of the furnace before using them, and close them when the pipes are replaced. When opening the furnace door, we should pay attention to check the situation in the furnace, especially pay attention to the phenomenon of gas leakage, if the leakage is found, it cannot be ignited, but it should be checked and repaired in time to ensure the safety before ignition.

2, pay attention to check the flue of industrial boiler, can't have water or not and keep the flue open all the time. At the same time, no combustible and explosive products such as diesel oil, firecrackers and so on should be placed around the boiler, and safe passageways of sufficient area should be set aside.

3. Start the blower before igniting the industrial boiler and open the air valve on each burner. When igniting, we must pay attention to fire and so on. We must not put the cart before the horse in order to prevent explosion. Also note that the burner should be ignited and adjusted in sequence from top to bottom and from inside to outside.

4. When using industrial boilers, if the blower stops abruptly due to power outages and other reasons, all gas and air valves on the burner should be closed immediately and the furnace doors should be opened if necessary to prevent accidents.

5, the operating room should be equipped with a gas alarm, if found gas leakage of the county should close the indoor gas valve, and then find out the leak point and timely repair, in the course of its attention must not use open fire to detect leakage.

Oil-fired boiler maintenance methods "" A lot of companies because after the purchase of oil-fired boilers, Careless maintenance process, with the result that the useful life of oil-fired boiler is greatly reduced. So how should it be maintenance of the oil-fired boiler? The following article gives you a detailed analysis. After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler. Stop oil-fired boiler more than a month, maintenance of law should be dry, wet maintenance shutdown method can be used the following month. To schedule the maintenance period Microflame oven, schedule the water cycle, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Periodic inspection outage before the oil-fired boiler furnace, should be prepared to work the following three aspects: (1) review the registration technical dossier furnace boiler and boiler furnace usage understand. In order to fuel the transformation within the furnace boiler external inspection be aware, the general need to understand: the transformation of the electric furnace boiler design, manufacture, installation; boiler furnace revamping; boiler furnace use history and usage; boiler furnace water treatment case ; boiler performance and other rules and regulations. (2) Check before shutdown preparation. First, with the production schedule maintenance shutdown date, and then let the transformation of the normal furnace boiler shutdown program shutdown, but slowly disheartened. Injecting cooling method may be employed downcast water, replacing the water cooled furnace and the furnace into line ventilation cooling. When the boiler water temperature was reduced to 70 ~ 80 ℃, before drainage. Open all doors hole. When the door opened, to prevent warm water, steam jet man suddenly burns. Corresponding to the passage blocked pipe on the transformation test furnace boiler steam, water supply, sewage and other pipes and other run in the transformation of the electric furnace boiler. Blocked with shutter have sufficient strength to avoid being broken drum high pressure medium. To clear the blocking position is indicated. And other operational boiler furnace flue should be communicated reliably cut off. Also to clear the transformation of furnace soot and scale boiler by warm surface. (3) test preparation tools and lighting. In order to ensure the smooth entry inspection, the inspector should prepare the necessary equipment, tools, measuring tools and safe and reliable lighting devices.

Central heating hot water boiler pricess for heating in winter is an important measure in most parts of China. Hebei Guan China Fortune Foundation Limited mainly engaged in real estate projects, is a leading industrial town operators. Heating service is primarily aimed at the Group's residential housing and other real estate. With the full open sky Battle, continue to improve the proportion of clean heating, heating for the implementation of clean energy, China Fortune Foundation to purchase much-needed high performance hot water boiler clean and green products. After comparing a number of boiler plants, the best of the best, determined to cooperate with the fast boiler in abundant clean energy R & D experience in boiler party. Providing fast boiler SZS Series 2 gas hot water boiler according to the actual needs, respectively 58MW and 29MW.

A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .
