摘要:汙泥焚燒作为城镇污水厂污泥处理的主流技术之一，在我国得到越来越多的工程化应用，现阶段我国汙泥焚燒在进行工艺设计和运行情况模拟时，计算污泥（燃料）发热量、烟气组成和焓值等关键环节，多借鉴燃煤锅炉的熱力計算方法。熱力計算是工艺设计和工艺运行时模拟预测的基本依据，作为工艺设计过程的重要内容，其方法的修正和完善有利于提升工艺设计和运行调控的准确性和合理性。汙泥焚燒与燃煤锅炉燃烧过程和控制要点均有差异，燃煤锅炉计算方法忽略了烟气中水蒸气的潜热，故采用燃煤锅炉熱力計算方法的准确度有待验证。分别采用传统燃煤锅炉的熱力計算方法和优化后的方法进行了计算示例比较，当采用燃煤锅炉的熱力計算方法进行汙泥焚燒的工艺计算时，由于未考虑烟气中水蒸气的实际状态和潜热，影响焚烧炉燃烧温度、烟气余热利用和烟气净化各环节的温度预测的精确度。我国汙泥焚燒入炉含水率的常见区间为50%~60%，采用传统方法计算时，从燃烧温度到后续烟气设施对应的入口和出口温度均偏高40~50 ℃。当采用传统方法进行设计和运行时，应结合入炉含水率的选择，充分考虑到由此引起的偏差。
Abstract:Sludge incineration, as one of the main sludge treatment technologies in urban sewage treatment plants, has been widely applied in engineering in China. At present, coal-fired boiler thermodynamic calculation method is often referred to calculate the key parameters (such as calorific value of sludge or fuel, composition of flue gas and enthalpy value) in the process of design and simulation. Thermal calculation is the basis of process design and simulation. As an important part of process design, modification and improvement of the method is beneficial to improve the accuracy and rationality of process design and management. There are differences in the incineration process and management between sewage sludge and coal incineration in coal-fired boilers. The calculation method of coal-fired boilers ignores the latent heat of water vapor in flue gas, so the accuracy of coal-fired boiler thermal calculation method needs to be verified. A comparison between the traditional thermal calculation method and the optimized thermal calculation method was exemplified. The actual state and latent heat of water vapor in flue gas were not considered when the coal-fired boiler thermal calculation method was used for sludge incineration process calculation, which affected the temperature prediction accuracy of incinerator combustion, flue gas waste heat utilization and flue gas purification. Common range of sludge water content to be combusted in the furnace in China is 50%-60%. The combustion temperature and the corresponding inlet and outlet temperature of flue gas facilities were 40-50 ℃ higher when the traditional method was employed. When the traditional method is used for design and operation, the deviation caused by calculation should be fully considered in combination with the selection of sludge water content to be combusted in the furnace.
