Gas Condensing Boilers For Sale

6 tons adjusting a combustion gas steam condensing boilers for sale, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.

After gas-fired condensing boilers for sales for low-nitrogen transformation impact: environmental protection efforts continue to increase, the provinces and cities have introduced various environmental policies. Air pollutant emissions is one of the main issues of governance and environmental protection sectors. For gas-fired boilers for low-nitrogen transformation has also become popular, such as Beijing, Tianjin, Zhengzhou, Xi'an and other places are carrying out renovation work and out of the boiler. 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 boiler has gradually been used and popular. But not as long as the use of gas-fired boiler can, according to China's introduction of the latest air pollutant emission standards, Beijing and Tianjin, the Yangtze River Delta and other regions, and Zhengzhou, Xi'an and other cities ever to perform the most stringent air pollutant emission standards --30 mg / cubic meter. Many enterprises due to gas-fired boiler installation time relatively early, current nitrogen oxide emissions higher than this standard, however, when the burner exhaust emissions can not meet the standards formulated by the state, need to deal with the transformation of low nitrogen may continue to be put into use .

What is the excess air coefficient of condensing boilers for sale and boiler professionals work? Learning and understanding of the boiler, the following is mainly to answer some specific questions, which specifically is: What is the excess air ratio boiler? Its smoke is calculated, and what about? And, What are two boilers, not within the scope of supervisory inspection? Designed boiler work, which refers to what? What are the contents of their work? So, the next immediately to give a specific answer. 1. What is the excess air ratio boiler? Its smoke is calculated, and what about? Boiler excess air ratio, for the noun words, simply, is a boiler operation, the ratio between the actual and theoretical air consumption air consumption. For different types of boilers, it is not the same. For example, oil and gas furnace is 1.1, and the fluidized bed boiler, it is 1.1 to 1.2. As for the calculation of flue gas boiler, mainly related to combustion equipment type and fuel type two.

In the transformation process, side by rapid technical engineers FGR advanced combustion technologies, the use of flue gas recirculation and the outer loop is provided, withdrawing part of flue mixed with the combustion air, and then into the furnace through a burner, not directly part in the combustion, by reducing the effect of the combustion flame temperature to reduce the temperature and oxygen concentration, to achieve the purpose of reducing NOx generation. For now, for a large volume of gas condensing boilers for sales, low compared to the overall transformation of nitrogen to replace the boiler equipment will save a lot of costs. Fast boiler has a boiler in research and technology low nitrogen aspects of considerable industry experience, successful completion of the reconstruction project Dingzhou low nitrogen Erie boiler, significant cost savings for businesses.
