(1) The fuel heating trolley burner should be installed along the tangential direction of the bath. Baths 30 to 40 should be rotated at regular intervals (such as weekly) to prevent partial overheating of the bath and prolong the bath life.
(2) Apply refractory cement or asbestos gasket seal between the bath flange and the furnace panel to prevent molten salt from flowing into the furnace. It is not advisable to use a fuel to heat the nitrate furnace to prevent the carbon black and the nitrate salt from causing an explosion after the furnace tube is burned through.
(3) Salt holes shall be provided at the bottom of the furnace of the trolley to prepare for the discharge of molten salt in the event of an accident, and usually blocked with appropriate materials.
(4) The trolley furnace uses two thermocouples to measure the temperature of the furnace near the salt bath and the heating element.
(5) When using toxic baths such as cyanide, lead and alkali, a strong ventilation device should be provided.
