SZS series low NOx gas-fired saturated steam low pollution boilers startup procedure for fruit juice industry

Fruit and vegetable juice processing production lines and fruit and vegetable drying production lines are inseparable from the support of sufficient steam heat sources provided by industrial boilers. Yitong Fruit and Vegetable Juice Co., Ltd. was established in 2011, in Xianyang, Shaanxi Province. It is a branch established by Yantai North Andre Juice Co., Ltd. The company can produce 25,000 tons of concentrated juice per year. The products are exported to the United States, Europe and other parts of the world.

Low nitrogen low pollution boilers startup procedure revolution to lead the industry in fact so much importance to the APEC summit in nitrogen oxide emissions from the boiler is not accidental. Nitrogen oxide emissions into the atmosphere dissolved in water will generate nitric acid rain, caused extensive harm to the environment, causing huge losses to the economy. For the boiler, fuel combustion is the main part of the nitrogen oxides generated. However, in most cities, nitrogen oxide emissions from the boiler still remain at a high level, or simply just to reach deeper coal to gas demand, low nitrogen, low dust and other environmental requirements far not on the agenda.

The importance of energy saving steam low pollution boilers startup procedure steam boiler also the vast majority of current China to gas-based, not only high energy consumption and serious pollution. Chinese steam boiler and the current thermal power of approximately 72% to 80%, usually lower than the international level, and a uniform practical operating power only 60% to 65%, and even small steam boiler lower, and 15% to the level of the international 20% . There are generally high energy consumption under the main question of the formation of Chinese steam boiler the following: First, the selection of unreasonable steam boilers, low power form the actual operation of steam boilers are often operated under low load conditions in the practical application. The primary reason is because the use of the unit in the procurement of boilers, usually by using the maximum amount of steam boiler steam to the election, so it is simple to form a "big horse car" phenomenon, the formation of hot steam boiler power down. Because the design of a steam boiler, the maximum operating power is generally a multi-boiler heating power in the highest load of 75% to 100% of the operation. The low boiler load and overload power boiler operation will form drops. Second, the skills of burning steam boiler China steam boiler burning skills are not very current leader, boiler air ratio over too large. Excessive air ratio and added amount of flue gas, the flue gas away excessive heat, exhaust heat loss to increase, together will form the pollution increases, the flame temperature drops, the boiler heating power becomes low. Third, the boiler water quality can not guarantee that most of the steam boiler is equipped with a water softener equipment, soft water treatment equipment but the uneven quality of equipment, soft water equipment selection, some too small, so the formation of steam boiler water treatment to meet the national standards . Water quality standards will form boiler scale, affect the number of boiler steam boiler thermal power life will decline. Fourth, the level of automation of steam boiler China's current low level of automation steam boiler is relatively low, there is no appearance of some equipment operation monitoring. Because deficient show and manipulate the appearance of the boiler, some operating parameters can not be adjusted in time, the boiler can not operate in the best condition. Frequency and temperature compensation deficient active manipulation skills modern boilers, makes the best steam boiler steam load can not be reached. Steam boiler energy conservation is a long job, first and foremost still wants to build a factory steam boiler steam boiler to manipulate energy conservation through energy innovation skills.

You know descaling method Henan square steam low pollution boilers startup procedure fast it? You know Henan party fast steam boiler descaling solution? Once the boiler fouling dirty, not only will reduce the thermal efficiency, the normal operation of the system to bring security risks, but also the water treatment agent can not reach the metal surface, accelerated corrosion of metal speed. Therefore, and remove any fouling is an important prerequisite to ensure the safety and service life of equipment. Today to introduce a chemical cleaning methods. The method of chemical cleaning of the scope of the boiler unit and requirements vary with different parameters of the boiler, furnace or boiler is a new state of furnace operation, cleaning agents and cleaning process using different methods. Since all parts of the furnace are possible dirty, so in addition to the steam boiler system itself, cleaning should include furnace superheater and cleaning systems. In other words, from the condensate pump outlet, through the deaerator, until all the water pipes of economizer. Economizer, water wall, belonging to the boiler steam drum system. Chemical cleaning methods: 1, boiler cleaning detergent cleaning agent typically include inorganic and organic acids, inorganic acids used are hydrochloric acid, hydrofluoric acid, organic acids are citric acid, EDTA and the like. 2, corrosion of boiler chemical cleaning agents are generally inorganic and organic acids, which have cleaning capability, and have varying degrees of corrosion of metallic iron. Thus, in the boiler chemical cleaning process, some additives should be added to inhibit corrosion of the metal but not reduce the effect of a cleaning agent and cleaning deposits. Such additives are referred to as corrosion inhibitors. After washing the boiler, cleaning apparatus removed, the boiler into operation immediately. If not used immediately, it should be taken down protective measures.

Guidelines for Industrial Boiler Performance Improvement

In these cases, use judgment to set up the best conditions at normal firing rates. 4.2 EVALUATION OF THE NEW LOW O SETTINGS After the boiler has been set up for low 0 operation and returned to normal automatic firing, it is good practice to pay extra attention to the boiler for the first month or two until confidence is gained in the new operating mode.
