chemical balance di recovery boiler

Burner fault recognition and Remedy: Start the burner is a prerequisite for the normal operation of the chemical balance di recovery boiler, one supporting auxiliary burner gas boiler is the most important equipment. If burner fails, it may result in severe cases whole boiler can not be used. So, how to identify and exclude burner fault it? Fast boiler small series to answer your questions. First, if the boiler burner ignition failure to start three times in a row failed to ignite, it is determined that the ignition failure. Troubleshooting as follows: 1, the gas pressure can not be maintained if the phenomenon of misfiring in 3-5kpa, too high or too low will. 2, too much throttle burner ignition vain many times can easily lead to the phenomenon. 3, when using the burner, the ignition voltage if the ignition is not, or when the ignition electrode dirty or wrong position, there will be ignition failure. 4, valve block will promptly turned on the ignition when the normal, open and could hear the sound, no open flame, so if the boiler valve group fails, it will not fire. 5, there may be ignition failure caused by the ignition controller, if the ignition controller fails, it will not lead to the normal ignition.

Small Capacity Package Boiler

Industrial package boiler refers to a small capacity fast install boiler, of which most partswould been pre-assembled at workshop. Boiler is supplied in large components, site work will be simple. ZG manufactured small capacity package boiler can be applicated in many industrial areas such as food industry, textile industry, power plant, beer industry, chemical industry, etc.

In the process of cooperation with Lulu, the company has maintained a serious and responsible attitude and enthusiasm, any after-sales problems in a timely manner to communicate and resolve site or through the network. Lulu's relevant person in charge to give us feedback, we buy fast chemical balance di recovery boiler is not only fast because of strong party strength, but also because of the powerful party fast service, any improper operation can get our phone to remind party fast remote monitoring, this allows us to use very reassuring. --customer feedback

Fluidized bed combustion (FBC) technology has been widely used in China for heat and power generation since the early 1960s due to its wide fuel flexibility, excellent emission control and wide range of load adjustability. In the late 1980s, this technology is developed into circulating fluidized bed combustion due to its advantage in scaling up and higher efficiency. Nowadays, the total number of FBC chemical balance di recovery boilers put into operation in China is about 4000, and about 3,000 of them are CFB ones.
