If you know a little about chemistry, you may know that the sulfur content of oil and coal is roughly equal, but ask what low-temperature corrosion of oil-fired water tube oil boiler manufacturerss is much more serious than coal-fired boilers, for two main reasons:
1. 90% of ash in coal-fired boiler, especially coal powder furnace, is taken away by flue gas, sulphuric acid steam formed in flue gas is absorbed by fly ash in flue gas, so that sulfuric acid vapor in flue gas is reduced, and about half of sulfur remains in ash when coal is burned. When the oil is burning, the sulfur content in the fuel almost all changes to the ash in the SO2, fuel, the fly ash in the flue gas is very little, and the adsorption ability to the sulphuric acid vapor in the flue gas is very weak.
2. The hydrogen content of oil in the oil-fired boiler is about 11%-12%. The combustion of each ton of fuel oil can produce about 1 ton of water vapor, and the partial pressure of steam in the flue gas is higher than that in the case of coal-burning.
Daily maintenance of gas-fired water tube oil boiler manufacturersDuring operation, the gas-fired boiler should pay attention to the following points: (1) the gas-fired boiler does not allow positive pressure combustion or smoke injection in the furnace because it is easy to burn out the coal hole cover. (2) the bottom floor plane of the gas-fired boiler shall not be watered up in order to prevent damp corrosion. The gas-fired boiler shall be inspected every 2 weeks and every 3 months after the operation of the gas-fired boiler. (1) the gas-fired boiler shall be inspected and repaired in an all-round way after the operation of the gas-fired boiler every 3 months. (1) the gas-fired boiler shall be inspected inside and outside the boiler. If the pressed part of the weld, steel plate inside and outside corrosion phenomenon, if found in serious defects should be repaired in time, if the defects are not serious, the next time the furnace shut down repair, if found When suspicious, but does not affect the safety of production, records shall be made for future reference. (2) after inspection, boiler primer may be applied on the surface to prevent corrosion. 4. Gas-fired boilers and boiler base shall be painted at least once a year. 5, There are dry and wet methods for the maintenance of gas-fired boilers: dry method and wet method. Dry maintenance method should be adopted when the boiler is shut down for more than one month. (1) dry maintenance method: after boiler shut-down, the boiler can remove the water from the furnace, and the method of dry maintenance shall be adopted under one month. (1) dry maintenance method: after the boiler has shut down the furnace, Thoroughly remove the internal dirt, rinse clean, dry the furnace with a slight fire (be careful not to fire), and then apply a 10-30 mm diameter lump of quicklime. The plates are arranged and placed in the pan, without contact with the metal. The weight of quicklime is calculated at the volume of 8 kilograms per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed and checked every three months. If the quicklime is broken, it needs to be replaced immediately. When the boiler is re-running, the quick lime and the tray shall be removed. (2) Wet maintenance method: after the boiler has stopped the furnace, the boiler shall discharge the furnace water, thoroughly remove the internal dirt, rinse it clean, and reinject the treated water until it is fully filled. Heat the furnace water to 100 ℃, let the gas from the water out of the furnace, and then close all the valves, where the climate is cold, do not adopt moisturizing method, so as to avoid the furnace water Icing damaged the boiler.
Condensing steam water tube oil boiler manufacturers in order to save more fuel to improve combustion efficiency: In order to improve the combustion efficiency, saving fuel, the fuel quality should be controlled, uniform atomization burner. Non-pressure condensing steam boiler indirectly heated hot water boiler, combustor or the like. To achieve the above object, the following points should be noted: 1 to understand the combustion principle, adjusting the wind ratio of positive oil (gas), to achieve efficient combustion; 2, to maintain a good working condition of the nozzle, the nozzle is not easy too large or too small, the nozzle wear obstruction, carbon status, to ensure good atomization combustion conditions. 3, to maintain proper pressure or hydraulic, pneumatic or steam boilers, such as high or low oil pressure, and a hydraulic or pneumatic pressure is too large or too small, will affect the mixing of fuel and air uniformly. 4, to adjust the burner flame length brains spray angle size and shape of the combustion chamber with fire furnace chamber filled eye, achieve economic combustion. No black smoke, no soot, in the good sense of the coming year running.
