Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.
Depending on the operating characteristics of electric 6000kg per hour fired steam boilers, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.
SUMMARY gas 6000kg per hour fired steam boiler maintenance gas boiler twice monthly maintenance inspection item A. Fuel supply line: a filter cleaning gas oil; ignition gas conduit 2 airtightness inspection; 3 checks whether the flow line... B. inspection of the instrument: a flushing water table; 2 Syphons flushing; valve experiment. C. Check burner:.... The flame detector (photocell) cleaning the light receiving surface; second inspection oil pump pressure is normal; 3 checks the combustion flame is normal; 4 check burner, the burner sound is abnormal; 5 Cleaning revolutions cup; 6 o'clock washing water rod. . Check D. Intake system: a washing water filter; 2 reaches rated pump head and flow; 3 a check valve is working properly... E. daily drainage tank and the cleaning debris. Water quality testing, water testing furnace. F. Check the combustion consumption is normal. Every three months in addition to the maintenance items plus the inspection item inspection items: Electric Part A: 1 line is loose aging, failure; 2 check the reliability of electrical components, overload; Protection relay 3 is normal; B.... open soft low deactivation tank valve exclude sludge; C to test the boiler and then point interlocking means: 1. low water position; overpressure 2; 3 flameout 4. The exhaust gas temperature ultrahigh; D. et quality tobacco. detection: analysis of tobacco smoke constituents comprising temperature detecting tail, combustion is working properly checked. E. burner and boiler cleaning outer cleaning. Paul A. large projects each year hosts a body part of a comprehensive clean-up tobacco pipes, water pipes, front and rear smoke box, part of the furnace and the burnout chamber and smoke tubes ash collection. 1. inspection openings comprehensive inspection hole hand hole, manhole sealing soundness, and timely replacement of defective seals. 2. The overall comprehensive testing instruments, valves, comprising detecting pressure gauge and safety valve, the pressure controller and the electrode level controller tuning. Part B. burner: Burner cleaning turn round cup, ignition means, filter, pump, motor and impeller systems, throttle link means to add a lubricant. Re-awarded for combustion testing. C. access control section detecting electrical components, control lines, the control box clean ash collection, each control point is detected. D. water supply system maintenance water treatment plant to check whether water quality standards, a comprehensive clean soft water tank, to check the functioning of the pump and lift, clean check valve spool and so on.Free Chat
