What if there is wear and tear in the natural gas boiler? Detailed inspection is the key, as is fuel management. According to the operation condition and time of natural gas boiler, we can plan reasonable wear inspection. When using fuel, we strictly control the granularity of coal and limestone. The size of bed material should be strictly controlled. Boiler waste should be disposed of. The waste residue of the boiler must be treated before it can be discharged. Natural gas boilers should be installed where heat is used, easy to install. The hot pipe should not be too long. It should have a good insulation. The pipe shall be tilted properly from the hot water outlet to the end. The water supply source shall be equipped with a control valve. To discharge exhaust gases, the chimney of the natural gas boiler should extend to the outside and the outlet should be 1.5 to 2M higher than that of the boiler. If we want to reduce the influence on the water wall tube, we can adjust the air pressure and air volume properly, and effectively reduce the wear of the water wall. Check time is usually standby or downtime. Items to be examined include wall wear, furnace sealing and smoke leakage. In case of wear and tear, repair and welding are required to ensure the normal operation of low price fired steam boiler. Generally speaking, before combustion of natural gas boilers, fossil fuels, fossil fuels and bed and circulating materials should be filled in the combustion chamber at wind speed and strength. And stiffness of the air convection under full integration. Furnace bottom air device, inner core area upward. The movement in the outer ring region flows downwards along the water wall of the furnace, thus prolonging the residence time of the coal particles in the furnace. Mineral particles, a large number of ash powder and smoke contain a large number of fly ash particles, these continue to lead to rapid wear of water-cooled wall tube, make wall thickness wear thin, resulting in wear.
Coal-fired boilers to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.

Central Government institutions funds, finance, public service vehicles, the state-owned assets and real estate management, service management is responsible for the specified life of the party and state leaders as well as services related objects.
When the weather gets colder and colder, people will choose different ways of heating, one of which is more convenient is the fuel-fired boiler, but many people do not understand his use, so take a look at the following. Classified oil-fired boiler is a kind of boiler with many kinds of oil such as diesel oil, waste oil and so on. Its general structure and arrangement are similar to coal-fired boiler, and the common classification is mechanical type and steam materialized type. The characteristics of the bottom of the oil-fired boiler are to make the bottom of the furnace inclined to the back wall, which is the bottom of the heat preservation furnace, in order to obtain good combustion characteristics. This kind of boiler, for those who don't have a natural gas pipeline, Hope the boiler can run normally low cost, then the fuel-fired boiler is a very good choice. The fuel-fired boiler is an important symbol of the progress of the times, in order to serve the human being well and further perfect according to the needs of the people. Oil-fired boiler is designed in accordance with certain commercial standards, to a certain extent to ensure the excellent boiler, but also to a certain extent to improve the heat absorption strength of the boiler, then how should we use it? Design problems according to the oil-fired boiler inside the design of the boiler inner tank is larger, can store steam will be corresponding to more, suitable load capacity will become stronger, can be To meet the needs of different users, the cleaning of internal gall is also more convenient. The fuel-fired boiler with fire tube structure adopts the structure of triple-reflux fire tube, and the flame burns in the combustion chamber with high thermal efficiency, energy saving and consumption reduction, so it is economical and convenient to use. According to the unique design of the boiler, the use of the oil-fired boiler needs to find a set of operation steps suitable for the boiler and give full play to its function.Free Chat
