20t Factory Direct Supply steam boiler Industrial Cambodia

Representation of Water pressure of Electric BoilerThe heating modes of the electric boiler are electromagnetic induction heating mode and resistance (electric heating tube) heating mode. The resistance heating mode is divided into stainless steel heating tube electric boiler and ceramic heating tube electric boiler, and the resistance heating mode is divided into stainless steel heating tube electric boiler and ceramic heating tube electric boiler. Resistance heating means the use of resistive tubular heating element heating. The electric boiler is easy to stack and combine in structure, control is flexible, maintenance and replacement is convenient. Because the newly bought electric boiler was not in use, the water pressure was almost zero at first, and the flashing yellow lamp (which was not aware of the fault number at the time and was estimated to be 10 according to common sense later learned) was unable to start. Finally, the black round water filling valve under the electric boiler was found, and the first water filling transition was made. Water leakage, and then the furnace water pressure self-adjusting to 3, but less than 10 minutes after the start of the failure, began to flash red lights, trouble No. 01, the phone consulted the dealer, said that there may be no power. After hanging up the phone, turn on the switch, the fault still exists. Doubting whether the water pressure is too high, so unscrew a set of heat vane above the discharge valve, adjust the water pressure to the accepted 1.2; Plug in the power supply, the red light still flickering, press the following prompt button after 3 seconds, troubleshooting, the system display is normal, so the power boiler restart, OK!

WNS Accident Analysis of dry 20t factory direct supply steam boiler industrial cambodia 1, the low level alarm and interlock protection device is not put into use and the failure is the leading cause of boiler provided with low water level alarm chain protection and low water temperature and smoke alarm device. Prior to the incident, said the fireman did not know the level of low water level alarm and interlock protection device has failed. Only because of the economizer outlet flue gas temperature exceeds its limit emerging (designed for 150 ℃), resulting in constantly ringing alarm bells. Fireman turned off the alarm, low water level chain protection device is also close together. Incident, fireman not effectively remind the water, the boiler continues to operate in the case of water, until the drum from collapsing, cracking convection tube squib. Therefore, the low water level alarm and interlock protection device is not put into use and failure is the primary cause. 2, fireman staff is not strong sense of responsibility and lack of experience is a secondary reason for not timely fireman check the health of the boiler, the water level of the false appearance also have not been ascertain. Even if the water level remains normal, but with fireman experience, should determine the average time in Sheung Shui and take appropriate screening measures, so that when the value is less than the fireman experience or did not do to duty. If you regularly observed from the observation hole to the boiler, you can discover the colors and deformation heating surface, and to take action if the boiler severe water shortages. Flue gas temperature alarm occurs first, without making fireman ascertain the cause, any breach of the rules is closed. Moreover, since a long time to eat off-site procedures are also not shift, so this is the responsibility fireman accident. 3, poor management, poor leadership and management is another secondary cause 1) as companies focus only on the production of steam consumption usually very strict, while ignoring safety management, there is no factory fireman personnel safety training. 2) The enterprise security managers no security certificate management, and knowledge of low water level and low water temperature alarm and smoke interlock protection device is not put into use, nor hamper it. 3) flue gas temperature alarm limit adjustment protracted problem, which is not as competent leadership and a great relationship. 4) boiler room management system, check system is not perfect, no preventive maintenance program, so that long-term drain valve leakage state; while the setting of boiler maintenance system, but not implemented, resulting in low water level alarm and interlock protection device is in low water failure state.

Beijing New Energy Automobile Co., Ltd. is China's first to operate independently and gain new energy automobile production qualification of new energy auto companies, mainly engaged in new energy vehicles and key parts and components research and development, production, sales and service business segments, and the layout intelligent manufacturing, energy management, smart travel, Internet +, and other strategic emerging industries. In the new energy automobile manufacturing process, and a series of paint drying processes can not do without the help of hot water boiler. Due to the company before the device has reached less than the growing production needs, the introduction of the 2017 mid-tail electric company producing heating pressure hot water boiler (CEDR0.7--95 / 70-Ⅱ).

2) Mechanical stroke firing

When fuel i.e. coal steam boiler furnace by means of mechanical stoker, the firing of boiler method is referred as mechanical stoker firing. There are mainly two types of mechanical stoker firing systems.
