Determining the right boiler is not a simple matter. After all, there are many aspects involved in purchasing a boiler. This requires communication with various parties such as technical design teams, companies, governments, etc. Here is a brief description of how to choose the right boiler.
1. First, you need to determine the type of boiler (hot water boiler, steam boiler, etc.). Customers can choose the type of boiler according to the application of the boiler, the environment, the company's industry and other information.
2. Capacity. The customer can estimate the boiler capacity based on information such as the environmental area of the boiler application (such as the area where the heating boiler needs heating and the size of the heating boiler).
3. Fuel. The fuel used in the boiler, the boiler that the customer needs to use (biomass, coal, natural gas, oil, etc.), which requires a combination of information.
What impact have fuel moisture steam boiler? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
Fangkuai boiler operation advantages 1, large font display water temperature, easy to grasp the boiler and system operation conditions, water temperature from 10 ℃ to 90 ℃ can be set at will, the boiler automatically to the system heating or to provide the user with hot water for bath. 2, the control system controls the start and stop of the circulating pump according to the furnace water temperature, when the furnace water reaches the set upper water temperature, the hot water circulating pump starts, and the hot water circulating pump stops when the water temperature is lower than the set lower temperature. 3. The horizontal gas-fired bath boiler is a three-way full wet back structure. It adopts the design of large furnace and coarse smoke pipe to increase the radiative heat absorption of the furnace and effectively save energy and reduce consumption. Use of threaded smoke pipes and Waveform furnace tank, greatly enhanced the heat transfer effect, greatly saved fuel consumption. 4, the whole machine is also equipped with overheat protection (when the furnace water temperature is super high, the burner automatically stops working and beeps to alarm, and the secondary overheat protection (when the boiler shell temperature exceeds 105 ℃, the secondary circuit is automatically cut off), When the boiler water is lower than the very low water level, the boiler stops working and gives a buzzing alarm), and the boiler leakage protection (the control system detects the electrical leakage, and when the short circuit is short, it will automatically cut off the power supply). 5, the boiler is designed according to the normal pressure structure, the boiler is in a pressure-free state, there is no danger of safety. Use of advanced centrifugal glass cotton multilayer protection Temperature, famous white color steel plate for outer packaging, less heat loss, beautiful anti-rust.
01. The gas-fired boiler should pay attention to the following points during operation: (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 of the gas-fired boiler shall not be watered up to prevent damp corrosion. 2, gas-fired boiler operation every 2 weeks, should be checked. 3, gas-fired boiler operation every 3 months after 6 months, the furnace should be shut down for comprehensive inspection and maintenance. (1) check the gas boiler inside and outside, such as the welds of the compressed part, the corrosion phenomenon inside and outside the steel plate, if found serious defects should be repaired in time, if the defects are not serious, it will be repaired the next time the furnace is shut down. If any suspicions are found but do not affect production safety, records should be made for future reference. (2) after inspection, the boiler primer may be coated on the surface of the water to prevent corrosion. 4, gas-fired boiler and boiler base paint at least once a year. 5, gas-fired boiler maintenance method: dry method and wet method, shut down for more than one month, should adopt dry maintenance method, shut down for less than one month can be used wet maintenance method. (1) dry maintenance method: after the boiler stops the furnace, put away the boiler water, thoroughly remove the internal dirt, rinse it out, dry it in the furnace with a slight fire (pay attention not to fire), and then it will be 10 mm in diameter and 30 mm in diameter. The small lump of quicklime is divided into plates, placed in the pan, without contact with the metal, and the weight of quicklime is calculated at the volume of 8 kg per cubic metre of the drum, and then all manholes, hand-holes, pipe valves are closed, Check every three months, if the quicklime is broken, replace it, and remove quicklime and tray when the boiler is re-in operation. (2) Wet maintenance method: after the boiler stops the furnace, it gives out the furnace water, thoroughly removes the internal dirt, rinses it, reinjects the treated water to the full, heats the furnace water to 100 ℃, lets the gas from the water drain out of the furnace, and then closes all the valves, Protection is not allowed in cold climates Wet curing method, lest the furnace water ice damage the boiler.
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
