Methanol plant with a capacity of 500 000 t/a at first stage completed of 3 boilers with each capacity of 130 t/h, having high temperature and high pressure circularly fluidized bed in the Henan Longyu Coal-Chemical Engineering Company Ltd. In allusion to that problems of stopping boiler and coking has occurred in many times due to blending, deforming of air distribution pipe, falling-off for blind plate of air pipe from pipe type assembly parts for back material of circularly fluidized bed boiler, technical reformation has been executed for back material system of boiler from original pipe type air distribution to such air distribution with plate air distribution adding air cap. Trial operation effect after reformation indicates that:①The operation is stable for back material system;no problem of stopping boiler exists;②Expense for replacing back material air pipe can be saved by 72 000 Yuan RMB annually and the expense for again start-up can be also saved by 8 million RMB in a year.
