Steam boiler three indicators and characteristics of magnetic drive fast boiler company Henan ready before the start of a centrifugal pump with small series to introduce steam boiler three indicators and characteristics of magnetic drive centrifugal pump Before you start to express the characteristics of the steam boiler, usually steam boiler capacity, parameters, characteristics such as reliability and economy indicators. In this example and several characteristic index defined steam boiler: 1, evaporation and steam boiler heating power: the size of the steam boiler capacity is typically rated represented evaporation. Rated evaporation refers rated parameters (pressure, temperature), under the conditions of burning design of the fuel and to ensure that the design efficiency, continuous operation should achieve maximum evaporation amount (per unit time steam production), should this be the rated output or evaporation plate, by the symbol "D" indicates the unit is t / h or kg / s. steam boiler plant and may also be supporting the thermal power turbogenerator, i.e. kw or mw represented. From the viewpoint of energy conversion of view, the ability to heat a steam boiler with a rated heat input, i.e., rated thermal power is represented by the symbol "Q", the unit is kw.Q = D (iq-igs) = D △ i, formula iq for export steam specific enthalpy (kj / kg); ig of feed water specific enthalpy (kj / kg) to different steam, water evaporation parameters is compared or additive, may be the actual steam evaporation D terms. "standard evaporated vapor amount" Dbz ", producing a predetermined amount of heat absorbed per 1kg no standard steam is 2680kg, so Dbz = D * △ i / 2680t / h or kg / s. and the hot water boiler are denoted by thermal rating the size of the boiler capacity, the symbol "Q", in units of MW, Q = G (is - ih) × 10 ?, where G is the amount of hot water boiler (kg / s), ihs, irs boiler out saliva enthalpy (kj / kg) .2, steam or hot water: parameter steam boiler steam production means at the outlet of the rated boiler steam pressure (gauge pressure) and a temperature of the boiler producing saturated steam, generally designated vapor pressure, by the symbol "P", in units of MPa, for the production of superheated steam boilers or hot water, and the need to indicate pressure steam or hot water temperature, the temperature to whom Economizer fingering water temperature, meaning that when the drum into the boiler without economizer temperature water temperature indicated by the symbol "t", the unit is ° C. Preparation ① Check magnetic drive centrifugal pump start before magnetic drive centrifugal pump connection bolts and anchor bolt without loosening .② pipe connection inspection is appropriate, whether the center of the pump and driver in processing temperature, cryogenic liquid pumps, pipe expansion, contraction may cause axial disorders, bite, etc. Therefore, the flexible pipe joint requires the use of direct coupling and centering etc. ③ small, when stopped, no major changes in the centering of the pump and the motor room temperature magnetic pump: while large, high temperature magnetic pump run and stop in very different axis, for the correct centering generally require warming to operating temperature after running or stopping the pump, to ensure rapid re-centering of the axis of both rotor consistency to avoid vibration and pumps the cleaning nip .④ piping must be first cleaned of foreign matter before running pipe, welding slag, Never push objects off the pump body human. gauge mounted on the screen before and after inhalation tube, in order to monitor the operation of filtration The blockage .⑤ disk drive. Before starting remove the coupling, rotation of the rotor by hand if there is abnormal, and the motor alone test, check if it is consistent with the rotational direction of the pump. Joint rotated by hand, can be found in between the pump impeller and the casing without foreign body, the disk drive should be uniform weight, no noise in the pump.

Is selected from the steam boiler heating gas boiler hot water boiler according to the output medium to distinguish, it can be divided into hot water boiler, a steam boiler. In daily life, many industries will be used in heating boilers, conventional heating, steam boilers and gas heating boilers can meet the basic requirements, but now using a hot water boiler. ? So in the end the election heating steam boiler or hot water boiler with a steam heating boilers, heat exchangers use more intermediaries do, in fact, reach the user's media is still hot, steam heating but has several disadvantages: 1, heating up too fast, heat is cold and hot temperatures, easy to leak. 2, the booster fast, easy to cause a heat sink metal fatigue life reduction, are likely to cause the radiator burst. 3, the water in the boiler heating fuel absorbs heat released, and the water molecules have to absorb some heat into steam, causing energy waste. Therefore, the use of heating hot water boilers for more energy-efficient than steam boiler, so one after another in recent years, some local steam boiler heating system to heat hot water boiler, steam boiler when the heat source is less and less, even extinct. But there are many like hospitals, hotels and other places need both steam and hot water needs, then choose steam boiler or hot water boiler is necessary to have specific analysis: If the hot water heating system using a large amount of steam required is very small, it is recommended another arranged outside the small hot water boiler steam boiler or low temperature waste heat recovery steam generator in order to meet the needs of a small amount of steam. Because based on actual experience, in addition to a steam boiler efficiency problem in itself a significant attenuation in the low load operation outside the state, the greater the loss of energy consumption, energy efficiency is generally only about 60%, serious waste of energy. Overall, commercial premises heating systems, gas hot water boiler to be more significant than the energy-saving advantages of steam boilers.

How is the use of electromagnetic steam boiler clean energy electromagnetic steam boiler is a clean energy, high efficiency, zero emissions of new products, has changed the past traditional low boiler efficiency, low temperature situation. The product can be used in hospitals, learning laboratories, Inspection and Quarantine and other steam heat sterilization industry. Electric heating low temperature waste heat recovery steam generator is an important new strategic product planning system energy companies, both uphold the company's green, Chi made the future of the brand concept, but also responded to the call of the new economic normality to promote industrial structure towards high-end, no precise control waste to energy saving and smart innovation combine. Function Advantage: compared to the resistance wire heating, heating power density of greater 90 seconds of the steam, saving more money! Common fired boiler takes 30 to 60 minutes of the steam. Zero emissions, green environmental protection, no annual filing. Ordinary coal-fired boiler pollution, high energy consumption, is the focus of national governance. Authority of the department, the thermal efficiency of the present device was 96.3%, can greatly save the cost of doing business consumption, energy efficiency <1t / h stratified combustion boiler 1 energy level than 15.89%. Germany's Siemens industrial control systems, a key to start, intelligent control. Unattended, automatic cleaning, 2 to 3 save labor costs. Cumbersome ordinary coal-fired boiler operation, to be full-time personnel to guard the core of this device heating water separation, will not cause leakage accidents. Resistance wire heating water and electricity are not part of the separation, heating tube long-term immersion in water, likely to cause leakage accidents, harm to human health. Explosive coal-fired boilers, the accident rate. The modular installation, you can actually use the steam situation, a single single-station for the steam according to the customer, but also focus on more than one parallel steam supply, out of the box, saving space, cheaper capital costs!

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
