The common types of boilers are as follows: fuel (gas) is fuel or gas as fuel, using burners to burn fuel, as a heat carrier. Generally divided into vertical, horizontal two structural forms, mainly according to the equipment space height of these two forms. Coal combustion is coal as a fuel, as a heat carrier. Generally divided into vertical hand-fired horizontal cylinder type horizontal machine burning three types of coal-fired structure mainly according to the labor intensity of coal so as to divide these three forms. For an electric heating oil furnace, heat is generated and transmitted by the immersed electric heating element. As a medium, the circulation pump is used to force the liquid phase circulation, and the heat is transferred to the oil furnace. Using one or more heat-using equipment, after unloading with the heat-using equipment, re-passing through the circulation pump, returning to the heater, re-absorbing heat, and passing it to the heat-using equipment, so that the continuous transfer of heat can be realized and the temperature of the heated object will be raised. Meet the process requirements of heating.
It is understood that around prevention and control of air pollution, ecological Environmental Protection Office of Shaanxi Province has formulated the "Boiler Air Pollutants Emission Standards" ( "Standards"), amended the "off key industries in the region of atmospheric pollutant emission limits." In the future, biomass, alcohol fuel boiler emissions also be included in "Standards".
"Standard" is to integrate and improve the local air emissions standards boilers. "Standard" for the scope of the province, covering coal, gas, oil, various types of fuel such as biomass; using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.), gas-fired boiler with reference to the implementation of emission limits.
After calculation, coal-fired thermal power boilers in Shaanxi Province implementation of the new standards, particulate matter, sulfur dioxide, nitrogen oxide emissions respectively about 0.67 tons 15,200 tons, 1.26 tons, down 27%, 40%, 21%; Burning after transformation of coal boiler, particulate matter, sulfur dioxide, nitrogen oxide emissions can be about 01,400 tons, 1.42 tons 14,100 tons.
With the haze pollution reduction work to promote strong, Shaanxi Province coal-fired generating units and 20 steam tons / hour or more coal-fired boiler to carry out the transformation of ultra-low emissions, will gradually iron and steel, cement and other industries to carry over non-electric low-emission transformation, the original standard has been overtaken by change of environmental situation. Additionally, the Guanzhong area of glass, ceramics, bricks, gold and other industry, there are a certain number of kiln, its environmental requirements leniency.
The revision of the "off key industries in the region air pollutant emission standards", the abolition of the thermal power industry, coal-fired boiler emission limit requirements, these two sectors rose to individual standards province-wide.
It also increases the coke nitrogen oxide emission limits Chemical Industries, gold industry, glass and glass products, ceramic industry emission limits, increasing the concentration of tile industries and atmospheric pollutants conversion approach.
The new standards are expected coke chemical industry NOx emissions will decrease 70%, the sintering process the steel industry, the particulate matter, SO2, NOx emissions decreased by 50%, 72% and 67%, respectively.
At present, the progress of technology and the capacity of circulating fluidized bed boiler in China increase, domestic CFB boiler will gradually play a positive role in China's electric power production and environmental protection, ZG circulating fluidized bed boiler combustion technology in low NOx is mainly reflected in the reduction of NOx combustion emissions, specific measures in:
1.One or two wind layout optimization method: one or two wind layout optimization can improve the grade of air, which can not only strengthen the oxidation zone and reduction zone hypoxia burnout piecewise low NOx combustion effect, but also inhibit the temperature and the temperature at low nitrogen level, and high efficiency combustion of a high degree of unity.
2.Flue gas recirculation technology: the use of flue gas recirculation technology, an oxygen content of air is reduced to 17% to 19%, while maintaining the flow of state, strengthen the staged combustion furnace, and further promote the circulation of the fly ash amount inside and outside of the furnace, so that the bed temperature decreased, have beneficial effects on the low nitrogen and high desulfurization process.
3.Measurement and control system: by measuring the precise flow can achieve the following main purpose and effect of the secondary air flow can be measured: one or two; one or two wind can be adjusted accurately, the staged combustion can be precisely controlled; combined with the flue gas CEMS, can realize the closed loop adjustment; can keep unit in low nitrogen condition; coordination control the combustion efficiency of nitrogen oxide and boiler.
Gas-fired boiler air consumption calculation formula and its supply pressure: for gas-fired boilers this kind of boiler, the following learning and understanding will be carried out through a number of specific issues, and at the same time, it gives the correct answer in order to let everyone have to learn content, and thus, to increase their amount of knowledge in this area, but also be able to make progress in their learning and development path. 1. gas boilers and electric boiler dealers, two boilers, comparable it? Gas boiler and electric boiler, two boilers, is nothing comparable, because they have different characteristics and applications, therefore, can not be compared, I can only say that the circumstances in which the use of which is more appropriate . So, on this issue, that the answer is no, the answer is no. 2. Gas boiler, calculate the air consumption, whether or not there is a corresponding formula? Gas boiler, air consumption thereof is calculated, then, there is a corresponding formula, specific, and is: calorific value gas boiler gas consumption (per hour) = power * time gas boiler / heat value of fuel / gas boiler Therefore utilization, knowing the specific gas boiler tonnage size of its power, and then heat value of fuel taken 35.53MJ / Nm3, and the value of the utility boiler heat takes 90%, then the specific values can be calculated in air consumption.
