有机热载体炉操作规程（Operation regulation of organic heat carrier furnace） Operation regulation of organic heat carrier furnace Organic heat carrier furnace pressure is relatively low, medium temperature is high, and mostly flammable and explosive substances, and some are toxic, and a leak in operation, that will cause fire, explosion, causing casualties. Preparation of heat carrier furnace before ignition (1) inspection and preparation of internal and external parts of heat carrier furnace 1. the inside of the heat carrier furnace is exhausted and dried, the boiler and the collection box are free of sundries, the human hole, the hand hole and all the door holes are sealed, and the sealing filler is used to meet the medium requirement of the heat carrier furnace. 2. inspection of safety accessories and protective devices (1) the needle valve or stop valve in front of the pressure gauge is in full open state. The pressure gauge accuracy, range, dial meet the requirements, no pressure, the pointer back to zero. (2) the liquid level gauge connecting pipe valve is in the open state, the drain pipe valve is in the closed state, and the drain pipe is connected with the storage tank. (3) all kinds of thermal instruments are well equipped. (4) the thermometer and the automatic record check are qualified. The ultra mild and over pressure alarm and automatic protection device have been put into use, and the electrical control is normal for each contact. (two) medium test and cold cycle 1. medium test The quality of the heat carrier used in the organic heat carrier furnace is of great importance to the safe operation of the heat carrier furnace. Therefore, the heat carrier sampling and testing should be confirmed first: (1) whether the maximum use temperature of the heat carrier is consistent with the boiler heating conditions; the heat carrier allows the use of temperature at least 30~40 / C lower than the boiler outlet temperature; otherwise, the heat carrier will soon decompose and d
