Chemical Plant Boiler Water Wall High Temperature Corrosion What types of chemical plant relevance of metals in the construction of boilers in steam plant pdf water wall high temperature corrosion types are there? Chemical plant boiler water wall appeared high temperature corrosion phenomenon is a complex physical and chemical processes, analyze the mechanism of corrosion can be divided into sulfate type corrosion, corrosion in chloride and sulfide corrosion three types. 1, the sulfate corrosion occurs mainly due to corrosion is sulfate type like corrosion in the boiler water wall portions of the raw coal combustion to generate a basic substance pyrosulfate and sulfate compounds such as by a chemical reaction, the corrosion process usually have junction slag or the like coking phenomenon. 2, chloride-type corrosion in recent years, many scholars have conducted research, and have achieved fruitful research results. The results showed that when the high chloride content of the fuel, will produce a certain amount of hydrogen chloride in the boiler, and the boiler corrosive effect [3-5]. Coal boiler test results show that the chemical, the chloride content is less than 2/10000, the production of coal combustion is much smaller than the chloride content of chloride corrosion is generated, therefore, not because water wall temperature corrosion caused by chlorine contained in coal of. 3, sulfide corrosion combustion zone in the furnace within the range, when the unburned flame to the water wall erosion due to chemical action, unburned fuel will consume large amounts of oxygen, so that the outer surface of the waterwall vulcanized occurrence corrosion.

When the relevance of metals in the construction of boilers in steam plant pdf is used, it is necessary to pass the heat balance test. When considering the actual benefit of the boiler room, not only the thermal efficiency of the boiler, but also the energy consumed by the auxiliary equipment of the boiler should be taken into account. When the fuel is completely burned per unit mass or unit volume, the air demand calculated by chemical reaction is called theoretical air volume. In order to make the fuel burn in more contact with oxygen in the furnace, the actual air flow into the furnace is always larger than the theoretical air volume. Although the heat loss of incomplete combustion can be reduced by adding more air, the heat loss of exhaust smoke will increase, and the corrosion of sulfur oxide and the formation of nitrogen oxide will also be aggravated. Therefore, efforts should be made to improve combustion technology, Try to complete the combustion in the furnace with as little excess air as possible.

Industrial relevance of metals in the construction of boilers in steam plant pdf manufacturers and users are very concerned about this policy. In this case, ZG Boiler keeps on technology innovation and development. Each industrial steam boiler manufactured in ZG is strictly following ISO9001, CE, ASME and IBR Certification. Manufacturing eco-friendly and high efficiency industrial steam boiler is our major work and goal.

After the meeting, accompanied by dealers to observe the company's leadership in the clean relevance of metals in the construction of boilers in steam plant pdf laboratory, set comprehensive performance test platform (energy efficiency testing), the burner test platform, systematic energy saving technology and demonstrate real boiler room, Transfer Intensification testing center, centralized control system and other functions, the maximum test capacity of 40t / h, the maximum installed capacity of 40t / h, is to demonstrate, on a test basis technical research products, set in a comprehensive testing center.
