blast furnace gas fired boiler in uzbekistan

State all the more attention to environmental protection, to provide more excellent atmosphere, we respond positively to the country's environmental protection, promote the blast furnace fired boiler in uzbekistan from coal to gas project. Among the many boiler suppliers, we chose the fast boiler. First, the party quickly done very well in terms of cleaning the boiler, the second is fast side also very comprehensive after-sales involved. The optional gas boiler was used after running fully meet the needs of our pharmaceutical production, both energy-saving and environmental protection, but also a very high thermal efficiency, saved us a lot of fuel costs. --customer feedback

Coal-fired blast furnace fired boiler in uzbekistans 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.

3 macrotaxonomy steam blast furnace fired boiler in uzbekistan steam boiler fuel can be divided in accordance with the electric steam boiler, steam boiler fuel, gas and steam boiler; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small single, double return the vertical structure, large steam boilers and more horizontal structure of three return. Vertical fuel gas steam boiler burner set under way, double return configuration, fuel combustion, boiler stable; inserted spoiler smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reduce user cost. Horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, the combustion flame in the combustion chamber large positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving and economical use. Waveform threaded pipe and furnace structure, not only improves the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable.

Heating blast furnace fired boiler in uzbekistans should pay attention to what is running on coal gasification project, the cost of gas-fired boiler more and more people's attention, which mainly include investment costs and operational costs of the initial equipment. What is the cost? How much concrete include? The initial investment costs including financing costs of gas boiler purchase cost of the equipment purchase cost and construction cost of equipment, as well as gas networks. It should be emphasized that the cost of gas boiler ancillary equipment commonly used to adjust the pressure equipment, measuring equipment and burners, and procurement costs because of different brands vary. Construction costs are a major natural gas pipeline set of so-called gas network tariffs, it refers to co-ordinate government funds charged to gas customers. Due to the huge gas boiler gas consumption, the cost is very large, it has become a key factor in the development of gas-fired boiler users. The key gas boiler heating period operating costs is the cost of gas. The sales price of natural gas in different regions is different. But now, the cost of heating the gas is much higher than the cost of coal-fired heating heating enterprises. To sum up, gas boiler heating costs significantly higher than traditional coal-fired boilers. However, the clean fuel gas boilers, atmospheric environment conducive to the protection of the city, so in the long run, the use of gas-fired boiler heating is more economical.
