industry vacuum water tube boiler for sale

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

How to protect steam boiler steam boiler steam quality is much broader than the application of hot water boilers, hot water boiler is mainly used for heating and hot water supply and steam boiler applications covering all industrial, power generation and other industries. What usually buy boilers for steam boiler is required? It is undoubtedly the security, stability, high efficiency, long life, cost savings, etc. However, these requirements and are directly or indirectly related to the quality of steam. Quality counts of steam, because it can affect the smooth running of the system, firmly believed, the economy is also related to product quality, production of power and energy consumption. If the steam boiler users should not have given it some attention, certainly will trigger a series of follow-up questions boiler. 1) the presence of rust in the cleanliness of the steam pipe, when the residual carbonate deposits, there may be means slag debris and the sealing material, these impurities have valves, causing jamming equipment damage, the pipeline will increase abrasion. Approach means that the progress of cleanliness pipe filter, and the filter means for level. 2) dryness incorrect boiler feed water treatment, boiler level control of unreasonable and excessive short-term peak load and other factors will lead to a total soda boiler Teng phenomenon, making the boiler outlet boiler with water. When the steam active in the pipeline, the heat pipe will condense part of the steam added to the condensed water pipe. The condensed water with chemicals and other impurities may accumulate on the outer heat transfer equipment, heat exchange equipment impact power, and impurities in the deposited metal outer scarring apparatus, resulting in uneven heating of the metal surface, the number of shortened life. In addition, the presence of water vapor transpiration decreased enthalpy of steam, adding steam consumption; steam in the water will increase the water film thickness measurement of steam heat exchangers appearance, rated thermal resistance occurs. Separators installation progress is useful means of steam quality, efficient steam trap steam quality can progress to 98%. 3) purity of the air will be present in the steam system, since the occurrence of a steam boiler still inevitably contains a small number of air, together with the pipe and equipment will have to start air, system and equipment downtime due to internal vacuum suction air. Air very low thermal conductivity, is a poor conductor of heat. Air containing steam system, the steam will decrease with the production capacity of the equipment, will increase the corrosion of pipes, valves and equipment. System steam exclude non-condensable gases such as air and thus the most useful way means that the progress of the steam purity means and the air in the system. 4) stable pressure / temperature in order to ensure the process heating requirements, steam reaches the point of steam pressure shall demand value. Together, and steam pressure should not be too high, otherwise it will add steam consumption. When the steam contained in the non-condensable gas such as air, although the pressure gauge to show satisfactory, but lower than the temperature corresponding to the temperature corresponding to full. Send high pressure steam, low pressure steam. Into the supply of steam equipment to meet the requirements of a minimum and a stable pressure. This will not only satisfied the needs of production, but also to reach the energy saving effect. Suitable selection of the delivery pressure of the vapor pipe diameter and useful heat piping and valves, plus a reasonable hydrophobic emptying conduit, together with the use of a reduced pressure regulation point, the point can be achieved by vapor pressure / temperature stable.

This entalphy shown turbine outlet conditions 0,5 bar 85,4 C or 0,2 bar 85 C (vacuum) water must be cooled up to 50 C (inlet of boiler).

Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).
