horizontal multitubular steam boiler flue regulations

Guangdong brand hot water boiler of purchase to pay attention to what the problem? Many users purchase the brand hot water boiler, because the experience is no more, and often do not know how selection. Since the special multi-style hot water boiler, not the same layout In addition, the company is not the same, many people are not aware of how to buy the brand, following Shenzhen Victor Onward boiler company to teach you some tips to buy the brand. With a look: First, buy the brand for the hot water boiler, hot water boiler should first understand the layout should install the device settings conditioning in the use, maintenance should also be protected so that only the layout must be reasonable smoothly. Second, each steam hot water boiler is responsible for part of the money, and we will have consumed part of the way in the use of this unit will be hot water boiler in the purchase of the brand style special attention, to calculate good demand then buy the brand. Third, the key point is that there are a lot of hot water boiler equipment use some help to have a very good effect, sure drop with the best power consumption, saving power.

Combining these five aspects of the cost of inputs, it can be summed up 1 ton operating cost per hour of gas boilers: 262.5 yuan / hour + 3.3 yuan / hour +2.535 yuan / hour +8.33 yuan / hour +0.68 yuan / hour = 277.345 yuan / hour .

Around at 6:00 on November 22, Guang'an City, Sichuan Province Economic Development Zone Industrial Zone, a company Newbridge burst distillation kettle explosion, the roof 20 square meters of workshop collapse occurred, had not resulted in a fire, but there are four people were injured, It has been transferred to hospital for treatment.

Suddenly the accident, the specific reasons unknown, Guang'an City, the municipal government attaches great importance to the explosion, immediately launched an emergency contingency plans, multi-power Guangan Economic Development Zone, safety supervision, environmental supervision, public security and fire protection, first time to scene to carry out rescue and subsequent disposal.

Distillation pot is directed chemical production still pot used in this step, also has a greater risk of leakage and fire accident-prone equipment. In recent years, leaking reactor, distillation kettle and other equipment, fire, explosion accidents occur frequently, mainly because often kettle equipped with a toxic, harmful hazardous chemicals, the accident consequences more serious than the general explosion, either to persons or property caused serious irreversible effects.

Distillation is one essential step in many process industries such as chemical industry, brewing, paper, food processing, it will involve the distillation process. Steam boiler equipment for the needs of enterprises to provide a distillation excellent choice. Steam boiler steam output, after a series of treatment steps of cooling, purification, extraction, etc., provides excellent quality of distilled water, for the production needs.

Fang fast has a very rich experience in R & D, manufacturing and sales of natural gas steam boilers, since practitioners, R & D and innovation has always insisted on clean fuels. One condensing gas steam boiler, gas steam boiler water, ultra-low nitrogen gas steam boiler ...... date, more than 200 kinds of types of boilers.

Over-temperature protection, over voltage protection, abnormal power protection, scale online monitoring, frost protection, the water level is too high, too low to protect and increase water protection than the traditional four fifth protection mechanism, so a series of protective measures, all-round to ensure the safety and reliability of operation of steam boilers, select the users of our products is very much at ease, peace of mind.

The common corrosion of industrial boiler is mainly oxygen corrosion and scale corrosion, and the main measures to prevent it are as follows:

1 do a good job in water supply treatment: Dissolved oxygen, iron ions and low pH values in the feed water all contribute to corrosion of boiler metals. Therefore, water supply should be deaerated as far as possible, feed water pH value should be greater than 7; Attention should be paid to the control of iron ion content for the recovery of steam condensing water for feedwater. Sometimes the condensation water usually contains yellow rust water as soon as the steam system is started. At this time, it should be properly discharged until the iron content is qualified before it can be used as boiler feed water.

2 keep the water quality of the pot up to standard: Generally speaking, too high salt and chlorine content in pot water, too low or too high pH value and alkalinity will increase corrosion. Therefore, it is necessary to discharge water reasonably, maintain a certain pH value, alkalinity and PO43- content of boiler water in order to keep the quality of boiler water up to standard, which can not only prevent scaling, but also be beneficial to anticorrosion.

3 prevent subscale corrosion: After scaling on the heated surface of the boiler, the pot water infiltrated under the scale will be extremely concentrated at high temperature and chemical reaction will take place, resulting in all kinds of scale corrosion, but the coverage of the scale is often difficult to detect. Therefore, boiler scaling should be cleaned and removed in time.

4. To form a protective film on the surface of the metal: For newly installed boilers, a good cooking effect should enable the metal surface to form a complete passivation protective film. Under the operating conditions, when the pot water maintains a suitable pH value (generally 10 μ 12) and a certain amount of phosphate and carbonate, it is also helpful to form a dense protective film on the surface of the metal and slow down the corrosion. However, if the boiler water quality is not well controlled, especially if the pH value is too low or too high, the protective film will often be destroyed.

5 do a good job of shut-down and maintenance: The corrosion of many boilers is often caused by improper maintenance when the boiler is shut down, and the corrosion products produced when the boiler is shut down are often accelerated when the boiler is in operation. Therefore, when shutting down the furnace, the maintenance work must be done in accordance with the requirements of the regulations.
