Oil boiler is a boiler fuelled by light oil (such as diesel, paraffin), heavy oil, residual oil or crude oil. Oil boiler is heated by the burner, fuel oil atomisation is good, fuel combustion is sufficient, the chimney can not see the black smoke, so the oil boiler is green, energy efficient.
Fuel oil through the burner sprayed into the furnace was mist oil droplets, very easy to mix with the air and rapid combustion and sudden exothermic. Compared with the same parameters and the same capacity of coal-fired boilers, the thermal intensity of the furnace volume can be increased by about double. But in order to reduce the heat load of the burner area, so as not to overheat the water-cooled wall tubes in this area, so the furnace volume is only reduced by about 1 / 3. And because of the ash content in the fuel oil is very small, so as not to slag on the convective heating surface, so that the furnace outlet flue gas temperature of up to 1300 ~ 1350 ℃ and reduce the convective heating surface between the pipe pitch in order to increase the flow rate of the flue gas, which can increase the heat transfer coefficient of the heated surface to save the heated surface area and steel. In order to prevent spontaneous combustion on the coal economiser and air preheater by accumulating carbon black oil scale, generally these parts must be installed on the steam soot blower to maintain the cleanliness of the heating surface. At the same time, because the fuel oil does not coking slag, it can be made of membrane-type water-cooled wall made of micro-positive pressure (500 ~ 1000 N / m) boiler. It can eliminate the induced draft fan, only with the fan can exhaust the flue gas out of the furnace. If the overall shell of the boiler is made of thick steel, can also be made into a positive pressure (0.3 ~ 0.6 MPa) boiler, the overall structure of the boiler can be made more compact, mostly used in gas - steam combined cycle generator sets.
