If natural gas as hot flow boiler fuel choice, because the convenience of clean natural gas and fuel used in the boiler service life will be over 10 years; but if it is a boiler coal or other fuels, it will shorten the life of some. Further, the life of the boiler with the use of the frequency, the higher the frequency the shorter the life of the boiler, the greater the contrary. Late boiler maintenance is also very important for the life of the boiler, good maintenance will extend the life of the boiler.
The output power of the burner should be matched with the rated output of the hot flow boiler, and the shape of the flame, such as length and diameter, should be selected to suit the furnace structure. Supply the air needed for fuel combustion from the torch root to make the oil mist or gas and air mix evenly and quickly to ensure complete combustion.
At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam hot flow boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.
Coal-fired hot flow 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.
Aug 01, 2000 · The boiler pump must provide the total flow of the system (in this case, at least 40 gpm) plus whatever flow is necessary to keep the return water temperature as high as desired. If the piping in the zone has less resistance to flow than the pump head rating at the flow design, the pump will provide more flow for the pipes given resistance.Get a Quote

Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems.Get a Quote

A variety of issues could cause your boiler to leak water. It will depend on where the water is leaking from to determine the cause however you should never try to fix a leaking gas boiler yourself, always call out a Gas Safe registered engineer. The most common cause is a broken internal component, such as a pump seal or pressure valve.Get a Quote
the boiler has a burner with a 10:1 turndown ratio. When multiple boilers are used, care must be taken to assure proper proportional flow through each of the units. If flow is not properly balanced, wide variations in boiler firing rates can occur and, in extreme cases, the resulting outlet water temperatures may not be at the desired point.Get a Quote
