Our front-line consultants told us that many users when consulting heating with gas boiler, first ask, "I'm such a big heating area, you have several tons of boiler to meet ah?" And so, today, we have to 1 ten thousand square meters heating area, for example, the selection of several tons of gas boiler is a brief introduction.
In this chapter we focus on to tell you what the internal work processes natural gas industrial centrifugal fan boilers are: internal gas boiler control system is divided into three, namely, water control systems, access control systems, electrical control systems, complementarity between the three. Here we focus on the working channel to the gas control system under you on in, the system mainly by natural gas boiler gauges, ball valves, filters, valves, flow meters, burner, etc., belong to the main gas fuel combustion machine , the combustion temperature in the furnace along the furnace flue gas back to the combustion chamber via the first back into the first flue tube bundle, then by compression before turning into a second box-type smoke flue tube bundle, and finally through the convection heat transfer into the trailing smoke channel, the flue gases through a stack to the atmosphere.
The improvement of industrial centrifugal fan boiler thermal efficiency is considered by many users. It is believed that this problem is the research direction that every boiler manufacturer has been studying. When many users operate the boiler, they often find some new problems in the actual production process, but among all the problems, the most troubling thing is the phenomenon of higher exhaust temperature and lower thermal efficiency of the boiler. This phenomenon seriously affects our normal work, so what can we do to improve its thermal efficiency? What we need to know about this is that the best fit for low-temperature characteristics is synthetic molding. However, most of the synthetic molds are biphenyls, both of which are composed of biphenyls Complex benzene derivatives, whose vapors or their volatiles are highly carcinogenic, are strongly advised to choose oil-based products. Secondly, in the process of meeting the low temperature performance, the product also has a relatively high flash point requirements. In general, engineers recommend that the low-temperature opening flash point should not be below 200 ℃. Through the continuous research and improvement of its equipment by professional manufacturers, it is found that in order to improve its thermal efficiency, it is necessary to increase the heating surface at the tail of the boiler, such as air preheater and economizer. However, when the backhaul temperature of the organic heat carrier furnace body is very high, the economizer can not be installed, but the air preheater can only be installed to alleviate the situation. So if the boiler does not exchange heat with other low-temperature heating systems, the only way to improve energy efficiency is to add air preheaters. After adding air preheater, the velocity of flow can be increased accordingly, so as to ensure the boiler to work safely, reliably and stably, and the thermal efficiency of boiler equipment will be increased accordingly.
Around at 10:12 on February 28, 2019, Zhangjiakou City Chabei Management District Kai Austrian Energy Management Services Ltd. Taiwan 15 tons of steam biomass industrial centrifugal fan boiler drum due to the control zone tearing a serious accident, killing three people the death of four people were injured.
Currently seven injured in hospital emergency treatment, cause of the accident is still under investigation, rehabilitation disposal is also an orderly manner.
Heartbreak is that similar incidents happened from the last time, only 28 days.
At 15:30 on January 2019 May 2009 55 points, Zhangjiakou City Hall Ltd. Hong Mei generating boiler scalding accident, three people were killed and one injured.
Boiler special equipment is clearly defined our country, whether it is manufacturing, purchase, installation, operation or maintenance, have strict operating guidelines. Now many have adopted new boiler intelligent control, operational safety compared to conventional boilers, more convenient; but that does not mean foolproof, vigilant and master the correct method of application, in order to minimize accidents frequency. After all, the cost of each accident are living lives.
Recalling these events boiler explosion
March 3, 2014, Xingtai City, Hebei Province, a steam boiler explosion. Boiler plant razed to the ground, surrounded by multi-family residential buildings, factories affected by the explosion were destroyed. According to the injured introduction, cause of the accident may be due to faulty boiler and pressure control instruments not work, the pressure continues to rise, leading to an explosion.
