food processing natural gas vacuum fire tube boiler supplier

Run the vacuum hot water boiler reliability depends on these three areas: 1. In order to ensure the degree of vacuum inside the boiler, at the factory to create a rigorous inspection, the quasi gas leak detection, to ensure a sealed boiler tank production process. To maintain the degree of vacuum, and to prevent the event, the plant is equipped with a standard suction pump. When the vacuum tank hot water boiler body, the heat medium water is heated to 90 ℃, according to the degree of vacuum exhaust pump automatic operation of the tank, not only the air out of the tank, also the presence of dissolved oxygen in water to remove the heat medium, to keep certain negative pressure, produced inside the tank will not corrode. 2. Water is a heat medium by a special manufacturing plant impurity, oxygen, water softening treatment, in the production of disposable infusion, can be recycled at runtime, without generally no special filling. I visited the plant in the design of the user survey, a Shanghai Electrical Machinery Plant, 87 years put into operation a vacuum hot water boiler, use a decade overheated media never raise water, which can still work normally. 3. A heat exchanger in the boiler with special requirements, using SUS444 stainless steel tube, which requires a special process during tube processing. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate. Steam boiler fuel by category descriptions

The design of steam boiler is generally three-way, wet-back, eccentric furnace, asymmetric structure of different boiler forms will have its own unique operation mode and characteristics. Has its own certain operating principle. The recent weather is a bit abnormal, either snowy or haze, so, in this kind of weather, how does the steam boiler water injector function normally? Steam boiler water injectors have single and double tubes, usually. Several types of upper suction and pressure type, the application of single tube upper suction type, consisting of shell, steam nozzle, suction nozzle, backstop pad, mixing nozzle and jet nozzle several parts. The water injector is easy to operate and convenient to install. The water absorption height is less than 2 meters, the water temperature does not exceed 40 ℃. When injecting water into a steam boiler, it is necessary to open the steam valve a little first, so that a small amount of steam enters the water injector and ejects from the steam nozzle. The air near the steam nozzle enters with the steam and is discharged with the overflow valve, and a vacuum is formed in the water injector. The water in the tank is subjected to atmospheric pressure and enters the water injector from the suction pipe. Increase the opening of steam valve, a large amount of steam into the mixing mouth mixed with water. The mixture of water gets the kinetic energy of the steam and enters the nozzle at high speed. Because the inlet nozzle diameter gradually expands, the speed of mixing water slows down, the pressure increases to greater than the pressure in the pan, push open the check valve to enter Inside the pot. Use steam boiler at the same time also pay attention to its regular self-care. The above is the introduction of steam boiler in the operation of the water injector operation process and mode for you.

Our preliminary investigation when the other side is very interested in fast boiler, a number of fast-party research and development as well as outstanding patent cases in all industry sectors, we have confidence in each other quickly this brand. After the cooperation, but also the strength and each staff fully aware of the fast boiler of a good attitude, and cooperation in the box, very at ease. --customer feedback

The advantage is durable and never hot water boiler hot water boiler explosion hazard What are the advantages of it, its advantages is never the risk of explosion, do not carry out supervisory inspection, regardless of the pressure relief problems boiler room, save steel and simplify the process , then scrapped boiler, cancel water supply pump, power failure protection is good, durable, saving the user investment. Hot water boiler operation is very simple, bank up a fire, dust, water, ignition thanks to this step, when the bank up a fire is the first cleaning, the ash cleaned, and then filled with coal bucket coal door that is closed can. Economic and environmentally friendly vacuum hot water boiler is in line with the needs of social development, therefore, vacuum hot water boiler is also welcomed by the people, and its usage is very large, their own strengths vacuum hot water boiler determines its space development huge. Automatic heating, hot water boiler vacuum meter is automatically displayed temperature and pressure, the secondary vacuum hot water boiler 24 hours can be a stoker, a hot water boiler so that the vacuum can maintain a constant temperature all day, so the use of it will be more convenient. Hot water boiler system, each station change the hot water boiler according to the size of the load carried by each of the main regulator of the proportional band. The fuel conditioning subsystem using the hot water boiler and steam turbine power - Frequency electrohydraulic control system similar to the feedforward - feedback cascade control system. Master regulator proportional regulator, the steam turbine power - frequency electro-hydraulic control system of a frequency corresponding to a difference amplifier which corresponds to droop ratio with the steam turbine, the size represents the size of the hot water boiler with a load capacity, proportional band greater hot water boiler with a load capacity greater the amount of fuel introduced ;; feedback signal, and the power turbine - steam turbine a pressure signal introduced into the electrohydraulic control system in a frequency corresponding to that amount of fuel is rapid elimination of hot water boiler spontaneous disturbances. Hot water boiler power problem, we use a temperature controlled pump start and stop, try not to let the pump work when the low temperature, when the temperature reaches the set again to start the pump. The inner wall of the boiler thermal efficiency to reduce generation of scale is the main cause waste of electric boiler, or magnetic methods recommended softening boiler water treatment, not only energy, but also extend the life of the boiler.
