In order to ensure the normal use of szs series 2 ton water tube steam boilers in the cold season, it is especially important to prevent water tanks from being frozen and cracked in the use of steam boilers. Ordinary steam boilers are purchased by ordinary users. When the outdoor ambient temperature is close to or lower than 0 degrees Celsius, and in severe environments such as strong winds and heavy rain, drainage work must be carried out when the steam boiler is in use. Drain all the water out of the boiler to prevent damage to pipes, tanks and steam boilers. Users are required to read the phase carefully before using steam boilers Use the product instructions and use the boiler correctly in accordance with the code of practice, especially in the case of harsh environment with low temperature, please follow the following steps to prevent freezing and cracking of the water tank after the use of the product, please follow these steps to prevent the freezing and cracking of the water tank. The approach is to close the inlet valve, open the hot water valve, and adjust the water temperature control button to the low temperature position or the high water position. Then remove the safety valve, sewage treatment equipment to ensure that the water can be completely removed. When you re-use, be sure to install the safety valve. Of course, we should not ignore the safety inspection and maintenance of boilers and pipelines in addition to the corresponding anti-freezing measures for steam boilers. When they are not in use for a long time, they should not be ignored. Remember to close the inlet valve and discharge all the excess water in the boiler to prevent cold air from entering the boiler.
Chemical Plant Boiler Water Wall High Temperature Corrosion What types of chemical plant boiler 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.
cogeneration(CHP) in sugar industry
In technical terms, the amount ofenergy that can be extracted from bagasse is largely dependent on two main criteria: the amount ofprocessed cane and the technology used for energy production. Crucially, only the use of high-efficiency boilers generating extra high pressures and temperatures allows production in excess of thecaptive consumption of a mill. The cost ofboiler sand their installation is relatively high but, as shown by projects in Brazil and Thailand, capital investment costs may be recovered by revenues from electricity exports to the national grid in a period not longer than 5 years. On the other hand,the success of cogeneration by sugarcane mills is fully dependent on the existing legal framework and the prevailing electricity market rules.
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
