how much gas heating boiler
Gas oil-fired how much heating boiler room ventilation system designed along with economic development, energy supply and demand changes in the relationship between environmental protection requirements increase, electricity and oil and natural gas in recent years, increasingly used gas oil-fired boiler. The gas oil-fired boiler room design related to people's life and property security of the country, but also can ensure the normal operation of critical boiler. In addition to the location of the boiler room and capacity to meet the relevant specifications, the design of the ventilation system which is also an important element in the design of the boiler room. However, due to the content of conventional ventilation and manual specification relates to small, there is no specific calculation method is given, designed to bring some difficulties. In this paper, problems in this area, combined with engineering experience of the author, make some analysis, calculation and discussion, put forward their views, for your reference. 1. Design Principles gas fuel boiler room ventilation system
The greenhouse oil and gas how much heating boilers produced by ZG boiler have wns series boilers and SZS series oil and gas boilers. These two boilers are fast-assembly installation oil and gas boilers. The boiler body is small, occupying a small area, convenient operation and sufficient output. Oil and gas boilers use natural gas, petroleum and other fuels, fuel delivery is fast, and there is no ash residue after fuel combustion. The greenhouse oil and gas boilers produced by ZG boiler are very environmentally friendly. They adopt advanced low-nitrogen technology to achieve low-nitrogen emission from boilers, and the boilers are clean and clean. It is an environmentally friendly boiler.
Since the Shanxi provincial government issued "on the issuance of the People's Government of Shanxi Province, Shanxi Province to win the Battle of Blue Sky's three-year action plan", cities are actively responding to priorities and deployment. Jiexiu municipal government related departments have carried out remediation phase out coal-fired how much heating boilers.
Future, Jiexiu City departments should fully understand the situation of air pollution prevention and control of the seriousness and urgency of initiatives to further strengthen the work, work harder to accelerate the phase-out of coal-fired boilers; comprehensive investigation to the use of coal-fired boilers, find out coal-fired boiler unit, boiler type and capacity, device status, etc. and establish a sound accounting boiler, cleaning up coal-fired boiler plant are out of range, so that base clear, the situation is clear, should be eliminated to make sure that eliminated; to clear objectives and tasks , responsible units, measures, in accordance with the time node in an orderly way, and effectively perform their duties, earnestly implement the clean alternative heat sources, the removal of coal-fired boiler with a new energy escorts to carry out work at the same time; to actively coordinate electricity, gas sector, as coal-fired boiler users to implement clean energy transformation provides safeguards to ensure that coal-fired boilers out of the objectives and tasks completed on schedule, and improve urban air quality, and gradually improve the quality of life of the masses.
Coal-fired how much heating 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.
