One of the important parts of the boiler - comprising a unitary structure drum boilers and boiler auxiliaries two parts. In the boiler body, the two most important parts of a drum and furnace. We have previously explained before the hearth, and today we take a look at the drum it. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. Its main function is storage, a water separation, to exclude the water pan and brine sludge in operation, avoiding pot containing a high concentration of salt water and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In use, the drum often go through thermal balance test, the time to consider the actual benefits of the boiler room, not only depends on the boiler thermal efficiency, energy meter and the auxiliary boiler also consumed. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in the flue gas of the drum, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Future development will further improve boiler thermal efficiency of boilers and power plants, increase operational flexibility and level of automation of the boiler unit, improve the operational reliability of the boiler unit and auxiliary equipment, which are inseparable from the drum.
25 tph SZS condensing gas-fired firetube packaged steam boiler for non-ferrous industryAs the core equipment of the production project, the steam boiler provides heat energy for the production process such as thermal analysis and drying. Tianqi Lithium is the world's leading lithium-based new energy materials company, its business covers key stages of the lithium industry chain. The production base in Shehong, Sichuan is the starting point of Tianqi Lithium's business, with an annual production capacity of over 172,000 tons.Recently, Tianqi Lithium carried out comprehensive technological transformation for further expansion of production capacity. As the important equipment for production projects, the steam boilers directly affect the company's production capacity, which is the key target of this transformation. Therefore, Tianqi Lithium attached great importance to this project and held a public bidding, it planned to purchase a branch of energy-saving and environmentally friendly steam boilers. As a leader among the domestic steam boiler suppliers, ZOZEN won the trust of Tianqi Lithium with its huge production scale and unique products. The two parties signed a purchase and sale contract for SZS series steam boilers. Soon after, ZOZEN won Tianqi Lithium Industry's Anju project with its strong strength once again, and provided the same type of gas boilers. ZOZEN SZS series gas-fired steam boilers are well-made, safe and reliable. The boiler body is made of high-quality insulation material, and the energy-saving device added at the tail of the flue is used to effectively control the heat loss, so that the boiler thermal efficiency reaches over 98%.
China is now the standard content of nitrogen oxides are mainly three: 150mg / m³, 80mg / m³ and 3mg / m³. The nitrogen oxide content of the conventional gas boiler is about 150mg, and emissions of 30mg and 80mg belong to a low nitrogen gas boiler. Adding "premix" combustion gas boiler technology can achieve low nitrogen emissions.
New Year period, Tongchuan City, Shaanxi Province seized by special pressure class inspectors seize the time, nonstop, through the tireless efforts have seven working days, the time limit runs successfully completed the Tongchuan city water quality testing and inspection work hundred sets of heating boilers.
In recent years, with the state-owned enterprises "three for one industry," the pace of the transfer of a separate depth step by step, in 2019, Tongchuan City Gas Co., Ltd. and Tongchuan Mining Co., Ltd. together for the original Tongchuan Coal mining companies and construction companies and their subsidiaries heating boiler units of unified management, are responsible for heating in winter work Yintai District and Wang Yi district within the city limits and nearly 30 residential units.
After receiving the application of these reported that construction of heating boilers, special prosecutor of the city leadership attaches great importance to immediately convene all pressure classes held inspectors "to ensure safety, promote harmony" will mobilize, deploy test the backbone of the boiler units get together and reported in accordance with inspection, quantity, wide distribution and other characteristics, develop a reasonable and effective inspection plan, centralized arrangements for the inspection of boiler units, inspectors have extensive under the jurisdiction of the Meiyuan district, dragon community, nearly 30 residential and hospital infrastructure companies run first-line heating boilers, boiler to run one by one test, carried out investigation and security risks, all currently in operation has successfully completed a water quality testing and inspection of boilers, boiler inspection a total of 101 units, 90 water samples boiler. In the access to information process safety management of the outstanding problems that exist in the use of boiler units, in accordance with the relevant regulations and safety requirements of technical specifications, targeted proposed guidance. During the inspection the boiler, for general questions, on-site supervision and the use of units of the rectification. Meanwhile, the inspection found two Royal River Area of boiler pressure parts leak is still sick to run for the safety problems on the spot requires the use of units to stop using the site issued a "special equipment inspection and opinions notice" to use the unit under and timely reported to the Council and served on equipment safety supervision departments seat safety supervision departments to actively supervise the use of the unit for rectification, at present, the use of hidden problems rectification units have been completed, the re-examination confirmed that security risks have been eliminated, effectively guarantee the safe and stable operation of the boiler .
