Overview of 75 Ton Gas Fired Steam Boiler

75 ton gas fired steam boiler is designed and manufactured in ZG Boiler and it has obtained its own patent, and the brand is ZG. 75 ton gas fired steam boiler has a flexible fuel adaptability, it can burn blast furnace gas, natural gas, coke oven gas, residual oil, refinery fuel gas and so on.

Compare the expansion tank furnace oil and energy consumption standard gas thermal oil: oil furnace oil furnace gas in this kind of, I believe we are not unfamiliar to it, because, in its website article, is related to the and there is a certain degree of accumulation of knowledge, so, based on this, the following may wish to continue their study and work, and then give you some learning content, so that you can make yourself a new harvest. 1. Gas oil furnace, we should know what their specific? A kind of gas oil furnace oil furnace, we should know the specific content of relevant knowledge, which is mainly has the following, are as follows: (1) this kind of thermal oil heaters, which operate on the installation is very simple and convenient as long as its upper and lower portions of the combustion chamber body closed can. Therefore, the installation of its cycle, not very long. (2) Since the heating surface is the use of a disc which tube, but is a close-packed, so that in the use of the HTF, the factor of safety can be greatly improved. (3) combustion within the combustion chamber, for adiabatic combustion, which allows burning adequately performed and at the same time, to improve the thermal efficiency of the versus diesel boiler exhaust temperature well.

Battle for winning Blue Sky, effectively improve the region's ambient air quality; Ningxia Hui Autonomous Region developed and published a "region-owned coal-fired thermal power units reconstruction plan for the ultra-low emission" (hereinafter referred to as the "Program"). "Plan" put forward plans before the end of 2020, nine companies owned coal-fired power plant 25 thermal power units for ultra low emissions transformation.

By the end of 2020, all the region's coal-fired thermal power units with self-transformation conditions by upgrading desulfurization, denitrification and dust removal facilities, the concentration of pollutants in atmospheric emissions all meet ultra-low emission requirements; long-discontinued businesses in the pre-production must be restored owned ultra-low emission coal-fired units to complete the transformation; gradually shutting down key areas do not have the conditions for the transformation of high-polluting coal-fired captive power plants; emission concentration of air pollutants new coal-fired gas turbine generator set to achieve set emission limits; the country City and Ningdong Management Committee in conjunction with the region's environmental quality improvement requirements, and actively promote the transformation of ultra-low emissions to arrange more than 65 tons of steam per hour of coal-fired boilers.

After the completion of the transformation project, owned coal-fired power plants should entrust a third party consultant for technical performance, environmental effects, equipment stability, comprehensive assessment, evaluation findings and issue.

In order to encourage enterprises to increase efforts to transform ultra-low emissions of pollutant emission concentrations below the pollutant discharge limits set by the state or place more than 50 percent, halved implement environmental tax policy. At the same time, we encourage financial institutions to give preferential credit support, to support eligible owned coal-fired thermal power enterprises to issue corporate bonds direct financing, to raise funds for ultra-low emissions and energy saving. According to the regional administration of appropriate incentive funding arrangements, to ultra-low emission reduction projects included renovation crew around them, give appropriate incentives based on emission reductions, combined with local conditions to increase financial support.

"Plan" requires all localities and departments should strengthen daily supervision and inspection of law enforcement to prevent corporate fraud, is not scheduled to complete the transformation of the self-ultra-low emission thermal power phase-out, discharge permit authorities to promptly subtract the emissions permit, for non-compliance business severely dealt with according to the law, to the public.

Air Fuel Ratio Effect on Combustion Efficiency

Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
