Step K: When the water washing has been completed, the pin-tube elements andfurnace floor must be cleaned with alkaline water because the washingwater is very corrosive.Step L: It must be ensure that all the washing water is drained away and looseneddeposits are removed from the furnace floor by looking into the furnace.Step M: Mount the inspection hatches on the smoke outlet box and secure them.Step N: Swing the burner back into position and dry out the boiler by starting theburner fan in manual operation for approximately 15 minutes. It is essentialthat the boiler is dried out immediately after water washing. This is becausesoot formations produced by an oil burner, contains sulphur compounds.Any residual soot and water will therefore react chemically to form a highlycorrosive sulphuric acid.Step 0: Check that the furnace drain pipe has not become blocked and close thedrain valve. Ifthe drain pipe at the furnace bottom is provided with a plug itwill be necessary to swing out the burner again to insert the plug.Important: Tbe refractory in the furnace must be heated slowly up in order tolet the water absorbed by tbe refractory evaporate slowly.Step P: Within the first hour; start the burner at minimum load for one (1) minute.Then stop it and wait for three (3) minutes before restarting it again.Step Q: Within the second hour; start the burner at minimum load for two (2)minutes. Then stop it and wait for two (2) minutes before restarting it again.Bước R: trong vòng ba giờ; bắt đầu ghi ở tối thiểu tải cho hai (2) phút.Sau đó dừng lại và chờ đợi một (I) phút trước khi khởi động lại nó một lần nữa.Bước S: cuối cùng đã bắt đầu ghi ở tối thiểu tải và để cho nó hoạt động ở đó tải chohai giờ tiếp theo.Bước T: lò hơi bây giờ có thể được đưa trở lại vào dịch vụ bình thường. Trong quá trình bình thườngkiểm tra hoạt động nhiệt độ khí ống khói là bây giờ trong chính xácgiới hạn.
