The anticorrosion of the valve body mainly depends on the choice of material. Although the material is very rich, it is not easy to choose an appropriate one for the complicity of the corrosion. For example, the sulfuric acid produce strong corrosion, when its concentration is low while its concentration is at a high level, it will produce a passive film for the steel. The hydrogen is the same ,when in high temperature and pressure, it will corrode the steel. Another example is chlorine ,chlorine has strong corrosion in wet condition. So many material can not comply with the requirements. Therefore, when the user choose a fuel chemical reaction of fire tube boiler, the corrosion material is the key factor to consider,but it is not the only one. Besides the temperature resistance and the pressure resistance and the economic factors should also take into account. Secondly, equipped with lining,the line material can be lead, aluminum,engineering plastic and so on.
Secondly, fuel chemical reaction of fire tube boiler parts are also very important, they will not only affect the overall operating efficiency of the boiler, but also the impact on the price of the boiler. It is important to know that boiler operation is never only possible with boilers. The operation of the boiler requires the formation of a complete scientific system, which requires many boiler fittings. Usually the main boiler accessories include burners, economizers, water treatment devices, valves and meters, superheaters, deaerators, air preheaters, etc. ZG boiler can provide complete boiler and boiler accessories.
15 tph coal-fired water tube fuel chemical reaction of fire tube boilers for paper industrySteam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. , Ltd. is one of large paper mill in Thailand, producing pulp, mechanical pulp, paper, board. Steam is an essential element in their production process. With the expansion of business and scale, the paper mill's demand for steam is increased by years. Therefore, Thai Development Industrial Paper Co. , Ltd. needs to order several sets of new steam boilers. Coal is used to be the boiler fuel in this paper mill so that they pay great attention to the combustion efficiency. After knowing their actual situation, ZOZEN’s sales manager has supplied 15tph SZL series water tube steam boilers for the company. This series of steam boiler is adaptable for all kinds of coal. Unique chain grate produced by ZOZEN is adopted for the fuel to be fully burned. Meanwhile, rational air register is designed to improve combustion efficiency. The thermal efficiency of ZOZEN’s coal-fired steam boiler is 5% - 15% higher than other original coal-fired boilers.
Since the Shanxi provincial government issued "on the issuance of the People's Government of Shanxi Province, Shanxi Province to win the Battle of Blue Sky's three-year action plan", cities are actively responding to priorities and deployment. Jiexiu municipal government related departments have carried out remediation phase out coal-fired fuel chemical reaction of fire tube boilers.
Future, Jiexiu City departments should fully understand the situation of air pollution prevention and control of the seriousness and urgency of initiatives to further strengthen the work, work harder to accelerate the phase-out of coal-fired boilers; comprehensive investigation to the use of coal-fired boilers, find out coal-fired boiler unit, boiler type and capacity, device status, etc. and establish a sound accounting boiler, cleaning up coal-fired boiler plant are out of range, so that base clear, the situation is clear, should be eliminated to make sure that eliminated; to clear objectives and tasks , responsible units, measures, in accordance with the time node in an orderly way, and effectively perform their duties, earnestly implement the clean alternative heat sources, the removal of coal-fired boiler with a new energy escorts to carry out work at the same time; to actively coordinate electricity, gas sector, as coal-fired boiler users to implement clean energy transformation provides safeguards to ensure that coal-fired boilers out of the objectives and tasks completed on schedule, and improve urban air quality, and gradually improve the quality of life of the masses.
