水煤浆锅炉的能效分析 总被引:1,自引:0,他引:1
通过定量和定性计算分析水煤浆水分、磨煤电耗、锅炉运行热效率以及锅炉运行电耗对锅炉能效的影响,并与链条炉排锅炉和煤粉锅炉比较,指出水煤浆替代重油燃烧虽可取得明显的经济效益,但在能效方面却不及燃烧制浆原料煤的链条炉排锅炉或煤粉锅炉。 相似文献

The paper presents the results of experimental studies of energy (calorific value, ignition delay times and threshold ignition temperatures, duration and temperature of combustion) and environmental (CO2, NOx and SOx emission) characteristics of fuel slurries based on pulverized wood (sawdust), agricultural (straw), and household (cardboard) waste. Wastewater from a sewage treatment plant served as a liquid medium for fuels. Petrochemical waste and heavy oil were additives to slurries. The focus is on obtaining the maximum efficiency ratio of slurry fuel, calculated taking into account environmental, cost, energy and fire safety parameters. All slurry fuels were compared with typical coal-water slurry for all the parameters studied. A comparison was also made between slurries and traditional boiler fuels (coal, fuel oil). The relative efficiency indicator for waste-based mixtures was varied in the range of 0.93–10.92. The lowest ignition costs can be expected when burning a mixture based on straw, cardboard and oil additive (ignition temperature is about 330 °C). The volumes of potential energy generated with the active involvement of industrial waste instead of traditional coal and oil combustion are forecasted. It is predicted that with the widespread use of waste-derived slurries, about 43% of coal and oil can be saved. 相似文献

During the years of oil shortage and rapidly increasing oil prices, the need to decrease dependence on oil-fired utility boilers became an urgent concern. The alternatives were to:
- 1. (1) build new coal-fired stations;
- 2. (2) modify oil-fired boilers to fire pulverized coal;
- 3. (3) modify oil-fired boilers to fire coal slurry;
- 4. (4) modify boilers to fire deeply cleaned, finely pulverized coal; or
- 5. (5) fire coal-derived liquids.
