Coal-fired 1000kg 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.
In 2018, Xinjiang Uygur Autonomous Region is located in Changji City, conscientiously carry out the central environmental inspectors look back to work, determined to win the battle pollution prevention and control, through the implementation of remediation coal-fired 1000kg fired boilers, industrial mentioned standard treatment, clean energy alternatives, smoke dust pollution control and many other measures to make the city's ecological environment has been continued to improve air quality.
Since 2018, Changji City in order to improve environmental quality at the core, the central environmental supervision as an opportunity to take environmental protection interviews, special inspection, etc., to strictly implement the main responsibility for environmental protection and various functional units of the company, by continuing to carry out law enforcement inspection, crack down on destruction of the ecological environment and harm public health violations, to further improve the regulatory environment grid system, to fight pollution prevention battle. 2019, Changji City to further increase the transformation efforts "coal to gas", "coal to electricity" and other areas, have been in Town sulfur heating station implemented the "coal to electricity" project, Onishi canal Heng Xin heat, Motor City nine branches, the benefits of grain and oil company implemented a central heating alternative project, blue mountains Tunhe polyester company implemented the "coal to gas" project.
Natural gas as a clean energy, can be reduced nearly 100% of the sulfur dioxide and dust emissions, 60% of carbon dioxide emissions and 50% of nitrogen oxide emissions, and help to reduce acid rain, global warming alleviate, reduce proportion of the amount of coal energy important energy; corresponding gas 1000kg fired boiler has gradually been used and popular.
Gas oil furnace gas consumption and related questions can automate operations: conducting oil furnace oil furnace gas this kind, it is also the product website and keywords, it is necessary to know and understand the subject, otherwise, can not be familiar with the site and its manufacturer. Therefore, in order to achieve this goal, the following will be introduced to the product description, so that we have to learn content, and thus, can be development and progress in their learning path. 12 000 kcal conducting oil furnace gas, if gas is natural gas which, then, the upper limit of the 1000kg fired boiler air consumption of natural gas, how much is? 200,000 kcal conducting oil furnace gas, if it is natural gas, then, the air consumption of the boiler gas limits are as follows: 200,000 divided by the gas heating value and thermal efficiency of the boiler, so as to obtain a particular value . If the boiler thermal efficiency is 94.8%, then, is the specific results of 24.8 cubic meters / h.Free Chat
