Boiler Supplier

Fuel gas factory price industrial boiler pool heater high degree of automation, higher operating costs than coal, small footprint, requiring less operator; while the gas boiler environmental factor is very high, is the fuel of the future of major equipment recommended.

Problems coal factory price industrial boiler pool heater gas boiler gas coal problems are: 1, more coal ash, 2, unevenness of coal particles, 3, coal contains a large amount of impurities, 4, a lower heating value of coal, 5 when combustion is not easy to ignite fire, 6, coal moisture content uncertain. 7, does not burn coal, slag high carbon content. In general, use is preferably designed coal boiler design coal or coal close, in order to ensure stable combustion. In recent years due to the growing tension surrounding the coal supply, coal supply has become diversified, coal quality is very different than before coal, have a great impact on the stability of the boiler combustion and normal heating operation. Impact of coal combustion boiler stable for: calorific value of coal is coal reflects an important indicator of good or bad, when the low calorific value of coal to a certain value, will not only affect the incomplete combustion instability and can lead boiler flameout, the outlet temperature of the boiler is difficult to compliance, affecting the normal operation. Volatile combustion and can be deposited at lower temperatures, as the combustion heat, the temperature rapidly increased coke particles, provide an extremely favorable conditions for ignition and combustion, volatiles further increased coke deposition and internal voids and the external reaction area, will help improve the speed of burning coke. Thus, the greater the content of volatile, nonflammable, the less fixed carbon in the coal component, the easier coal burning ember, devolatilization of many voids, increases the surface area of ​​the reaction, the combustion reaction is accelerated. When the volatile content is reduced, pulverized coal ignition temperature significantly increased, the hot increases, difficult fire, ignition time required becomes longer, the combustion stability is reduced, shifting the center of the flame, furnace absorbed radiation heating surface reduce heat, increase the heat absorption of the convection heating surface, the rear exhaust temperature, exhaust loss increases.

Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam factory price industrial boiler pool heater can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).

Coal-fired factory price industrial boiler pool heaters 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.
