摘要： A method of optimizing the scheduling time between sootblowing operations in a boiler having a plurality of heat traps, comprises measuring the instantaneous efficiency for each heat trap of the boiler, using a filter constant and the amount of load under which the heat trap is placed to calculate an average slope for the loss of efficiency between sootblowing operations and calculating an optimum scheduling period between sootblowing operations as a function of a cost factor reflecting the cost of a sootblowing operation, the duration of the sootblowing operation and the slope.

摘要： A method of identifying a parameter of a model for a rate of loss of boiler efficiency due to a sootblowing operation, in a boiler having a plurality of heat traps, comprises measuring a time since a last sootblowing operation in the heat trap in question, measuring an overall boiler efficiency at the beginning of sootblowing for the heat trap in question, measuring a change in efficiency due to the sootblowing operation and calculating the parameter using an equation. According to the equation, the ratio of efficiency change over overall boiler efficiency equals the time factor since the last sootblowing operation times the parameter minus a summation of factors for each of the other heat traps and their associated sootblowing operations. The technique is extendable to individual sootblowers within a heat trap by using fouling rate index rather than overall boiler efficiency.
摘要翻译：在具有多个热阱的锅炉中，鉴定由于吹灰作业造成的锅炉效率损失率的模型参数的方法，包括测量所述热阱中最后一次吹灰作业后的时间，测量在所述热阱的开始开始时的整体锅炉效率，测量由于吹灰操作引起的效率变化并使用等式计算参数。根据该方程，效率变化与总体锅炉效率的比率等于从最后一次吹灰操作乘以参数减去每个其他热阱的因子和它们相关的吹灰操作的总和的时间因子。该技术可以通过使用污垢速率指数而不是整体锅炉效率来扩展到热阱内的单个吹灰器。
