How to use gas-fired boilers can improve the thermal efficiency of the gas boiler is also bad choice will directly affect its thermal efficiency, so we are in the process of buying, be sure to choose good quality. In fact, the factors affecting it improves the thermal efficiency of many, so we regularly thermal conductivity of the gas boiler for cleaning and maintenance, etc., so as to extend its service life. Selection of good thermal and oxidative stability, strong anti-coking. Be careful not to choose odor and color depth of the election furnace. Life with carbon residue, an acid value, flash point, viscosity 4 measure. Make semiannual oil testing, in order to grasp the good quality operation. Identify problems and timely replacement, and find out the reasons and preventive measures in advance deterioration. At the same time it must strictly do not mix different product numbers to use. When used in strict accordance with the rules furnace, to avoid emergency fire heating (temperature rise rate which should be controlled at l0 ~ 40 ℃, h), over-temperature, over-pressure, to take emergency shutdown measures quickly and decisively, always observe the oil level and the oil expansion tank temperature. Such as the lack of oil should be added. Prevent air and water into the oil circulation system. It will accelerate the reaction (the oxidation rate at two-fold increase for each increase in L0 deg.] C temperature) after direct contact with air because of high temperature, high temperature oil to prevent direct contact with air. A better approach is inflated with nitrogen gas to the upper space of the sealed tank. Forming a protective gas layer, sealed under nitrogen unconditionally. To header tank temperature generally does not exceed 60 ℃, header tank is not directly connected in series within the circulatory system. Improve the thermal efficiency of the furnace hot oil boiler, timely removal of the inner wall of the furnace, plate line grime on the walls, in order to ensure good heat transfer, and should use a better quality of gas as far as possible, so that the heat generated by the combustion of coal in time, fully passed to it.

Gas-fired steam boilers can be cleaned during cleaning using efficient and environmentally friendly non-corrosive detergents. This will cause the tube to expose the primary color of the metal and reduce the impact of dirt and bio-algal sludge. After ignition of gas-fired steam boiler, attention should be paid to observing the furnace temperature and the temperature of the main steam. With the increase of main steam pressure, the flue gas temperature of boiler is obviously increased after ignition. If the temperature does not rise, you should go to the scene immediately to inspect the oil gun fire. The scale thermal conductivity of a gas-fired steam boiler is only 1/10 of that of steel. This hinders heat transfer when it scales on a heated surface. In order to keep the boiler in use The output shall increase the temperature on the combustion side. The increase of outlet temperature of gas-fired steam boiler increases the loss of gas-fired steam boiler, and the scale on the water wall of equipment will effectively reduce the heat transfer effect, which may lead to the increase of the temperature of water wall and the burst of water wall. When a gas-fired steam boiler is in operation, a series of chemical and physical reactions will occur in the furnace. In use, it will effectively form a hard and dense scale on the heated surface, which will directly lead to its heat exchange. The reduced efficiency and corrosion due to scale will reduce the heat absorption of gas-fired boilers.
