boiler supplier

best steam boiler of power plant

Fast boiler based on the local, to the world. In 2013, Alliance Group and Indian steel companies entered into a collaboration to deliver four single 26.7 tons of steam shell type boilers, famous at home and abroad.

What are the advantages of a common hot water boilers and air heat pumps have? 1, if you are the best steam boiler of power plants, hot water heated by steam, the biggest advantage is cost savings for water treatment, thermal efficiency although almost, but it is still the most comprehensive savings. After the required heating bath of water vapor, the steam is condensed to be a relatively low temperature of the water, the water may be reheated directly back to the boiler. 2, if the direct use of hot water boiler, bath water directly from the hot water supply, will greatly increase the cost of water treatment - Without treatment, after long-term use, hot water boiler heating surface is bound to be a lot of fouling, affecting heat transfer and thermal efficiency. 3, air source heat pumps is the use of a compressor to heat the working fluid, if large quantities of water, it also faces the problem of water treatment. Taken together, if large quantities of water, or the first way is best.

Boiler Water Shortage Accidents szs water analysis 1, the low water level alarm and interlock protection device is not put into use and failure is the leading cause of the boiler with a flue gas temperature alarm devices and low water level alarm and low water level chain protection. 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.

stop the boiler to dry it :

2 hours before the boiler stoped,with the help of water supplying system and medicament system, the fireman add ammonia to the boiler to increase the PH value and ammonia concentration. In this way, a protection membrane will be formed in the boiler with which the corrosion caused by the boiler water will reduce during the idle time.
