boilers coal and diesel
There are a number of options available for the direct co-firing of solid biomass materials in large pulverised coal fired boilers coal and diesels, including: pre-mixing the biomass with the coal, added dedicated biomass mills, 100% conversion of one existing mill, parallel boilers, and gasification.
Around the city to promote the coal to gas project, the major institutions of the heating system put forward higher requirements. Central Conservatory of Music is available to students and teachers clean, safe, comfortable, energy-efficient heating environment, protect the health of teachers and students, to transform the traditional boilers coal and diesel treatment. Praise fast boiler Willie sharp series obtained in the transformation of low nitrogen boiler major institutions in Beijing, the Central Conservatory of Music in late 2017 with the signing of fast boiler boiler purchase contract, ordered six Willy sharp series V6-99, to for the entire school's heating facilities.
Steam boilers coal and diesel wear and electric test pump DSY Henan fast boiler's steam boiler small series with you about wear and DSY electric test pump wear is one common steam boiler heating surface defects, boiler heating surface is arranged in the boiler the furnace and the flue, in particular a heating surface in the steam boiler flue vertical tail, by the long brush smoke, soot in the flue gas so that the wall heating surface wear thinned, so that heat from the flue gas scouring wall ironed a phenomenon known as wear and tear. Flow rate, the concentration of soot in the flue gas and the hardness of the tube bundle arrangement such factors as the wear rate of the heating surface of the steam boiler and the flue gas is related to the flow rate of flue gas wherein the greatest impact on the wear of the heating surface. Experimentally measured, proportional to the cube of the wear rate of the heating surface tubes and the flue gas velocity, it is necessary to effectively control the flow rate of flue gas. Leakage of the furnace wall, a partial wall flue ash, convection heating surface partially severe slagging will cause a partial flue gas velocity is too large, so that the heating surface tubes local wear increased, further, when the soot blowers work failure, high pressure steam steam heating surface tube will blow erosion, so that the wall thinning. Heating surface tubes often wear area is: cool ash, burner, bullnose, and close to Manhole sootblowing waterwall tube aperture; a lower portion of the flue gas before the steering tube heating surface vertical chamber; vertical tail horizontal heating surface portion of the second row of three tubes of the flue, the lower portion of the second three tubes, tube support edge portion of the clip, close to the furnace wall side of the rows of tubes and the individual tubes and the like projecting tube rows. Heating surface wear reduction methods are: to reduce boiler load, reducing flue gas velocity; burning coal quality, reducing the content of fly ash in the boiler flue gas steam; change bundle arrangement, a staggered arrangement to the line arrangement; Clear slagging and blocking flue ash, flue gas flow area increases; leakage reduction furnace wall; the installation of a shoe or the spoiler like. Abrasion test on the electric pump plunger hole set DSY electric test checking pump plunger sleeve (1) Check the DSY type. If the pump DSY electric test has passed the test on sealing ST-990 or the tester 3,375,375, the plunger sleeve is available. If the leakage is large, it is necessary to replace the plunger and plunger sleeve. (2) using the burr, coke, and high-expansion magnifying glass to check the amount of deformation of the bore. When the metering orifice is damaged, DSY i.e. electric test pump is not working properly. Do not attempt to clean with a wire, plug, etc., should be cleaned with a solvent. (3) Check the fuel oil channel as well as choking loose plunger sleeve for cracks. (4) Check DSY electric test pump plunger sleeve surface endless belt black area and Degree how damage flatness. Some electric test pump head end of the barrel nozzle sump has been canceled. Henan is committed to fast boiler steam boiler manufacturing, product quality, reasonable prices and widespread industry praise, if you have any needs, please contact us!
About Henan low nitrogen gas boilers coal and diesel and the transformation of Henan low nitrogen gas boiler is upgraded on the basis of common furnace on it than the ordinary boiler biggest advantage is that the emission of nitrogen oxides. Henan low nitrogen gas boiler is divided into two: one is nitrogen oxide emissions below 80 mg; the other is a nitrogen oxide emissions below 30 mg. Of course, if you want to achieve low nitrogen emissions, it must be met is to use low-nitrogen burners. From the development trend, Henan low nitrogen gas boiler into the mainstream as a winter heating, natural gas is not only energy efficient, low-carbon environment, the country can meet the heating needs of sustainable development and environmental protection are two simultaneous, consistent with the development of the cause of energy conservation ideas , winter heating will become mainstream products in north and south China regions. In response to the national "energy saving" the call, further reducing boiler NOx emission from the country are carrying the boiler to Henan low nitrogen gas boiler. Currently, low-nitrogen transformation technology boiler there are three: First, the two-scale low NOx combustion technology, mainly for Corner Tangential unit, by controlling the scale of the transformation process and on the spatial scale to achieve three characteristic difference, resulting in two furnace three beneficial characteristics forming the anti-slag, the NOx is low, steady combustion of the scale function. Second cyclone low NOx combustion technology, primarily for the opposed wall units, by replacing coal burner and the transformation of secondary air, tertiary air boiler to reduce the nitrogen oxide content. Third W low - NOx combustion flame technique, the longitudinal arch boiler pulverized coal burner to a low NOx combustion is replacing a specific structure, to reduce the impact on the normal operation of the combustion tissue as possible, the structure of the secondary air substantially constant. These three low NOx combustion technology in the transformation have made good Jiangdan effect. Now, there are many small boiler (100MW units and below, primarily in the form of Tangential) also need to be low-nitrogen transformation, but if using conventional low-nitrogen transformation technology, investment costs are relatively high for small boiler is concerned, may not be bear, economic efficiency will also be affected. In view of this situation, we launched a small-scale low-nitrogen transformation technology boilers, control and transformation through major processes affecting boiler nitrogen oxides produced with a smaller cost of renovation to achieve the purpose of significantly reducing the concentration of nitrogen oxide emissions boiler.
