Oil boiler in addition to good safety and technical measures to deal with electrical, fire and explosion, 防雷防静电 aspect, but also special attention to the following elements resulting in fire preparedness. Drum kits, burst pipe resulting in fire HTF storage, transport or maintenance work, perhaps not accidentally mixed with water and impurities. So, when the HTF temperature reaches a certain height, it will cause fuel injection and ignition, perhaps the heat of vaporization of water occurs pressure, resulting in an explosion overpressure device. In addition, assume that the residual carbon content exceeded HTF, 600,000 kcal organic heat boiler, oil will undergo chemical changes during the heating operation, generating few polymers, while coke formation due to overheating of some of these high polymer matter and carbon residue insoluble in HTF, will suspended in oil, the work of these substances may be deposited at the bottom of the drum and drum kits overheating, or deposited in the wall overheating burst pipes. Some companies use to improve the way to ensure the outlet temperature for the heat, the outcome of the outlet temperature of the heat carrier near to or even exceed the maximum allowable use temperature, then increase the heat inside the device with a coke, fouling extent that lower radiator heat power constitute a vicious cycle, until tube explosion. In addition, the low flow rate will constitute most of the heating surface of the tube wall temperature or somewhat higher than the permissible film temperature and shorten life expectancy HTF normal use, causing overheating resulting in drum kits, burst pipes. Outlet temperature high, the flow rate is too low. Talking about the temperature and pressure of a steam boiler, steam boiler temperature at a certain pressure, so water vapor in the boiler continue heating, fixed grate organic heat carrier boiler water temperature have been rising, and ultimately to the saturation temperature (also known as the boiling point or vaporization temperature), this water has a saturation temperature is called the saturated water. Steam boiler under condition of maintaining the pressure on the saturated water heating was continued organic heat carrier boiler, when the saturation temperature constant, but gradually converted to saturated water vapor, the saturated steam temperature is called saturated steam. Pressure remains unchanged, and heating was continued for saturated steam, may further increase the temperature of saturated steam, superheated steam making. For steam boiler superheater, marked on the product nameplate its temperature is "superheated steam temperature" in Celsius (℃). Since the saturated steam having a pressure corresponding to the saturation temperature characteristics, i.e., with the increase of the vapor pressure of saturated steam temperature rises accordingly. Therefore, each steam boiler "rated steam pressure" must correspond to a certain "saturation temperature" to help in the steam boiler superheater no longer the product nameplate label "saturated steam temperature." Second, the water vapor pressure of the boiler steam within the boiler to absorb heat released from combustion of fuel, when the liquid into a vapor, which is about 1800 times the volume will increase, and this because of free expansion of the boiler is a closed container limited, so that the boiler pressure parts to withstand the pressure soda effect. Steam boiler nameplate "rated steam pressure" is the maximum allowable operating pressure value boiler unit is megapascals (MPa). For steam boiler superheater, green horizontal organic heat carrier boiler, the pressure is the pressure superheated steam superheater outlet. For no overheating of the steam boiler, the pressure is the saturated vapor pressure of the main steam valve outlet. Once beyond the rated steam pressure boiler operation that is in danger, and even lead to the explosion.
