Recently, Shaanxi Province, to build a good ecological environment, issued a "Blue Sky Battle Shaanxi Province 2019 work program", "clear water Battle of Shaanxi Province 2019 work program", "Shaanxi Province Pure Land Battle 2019 work program", "Shaanxi Castle battle province 2019 work program "and other four major environmental battle to defend the program. Details below.

"Program" is mentioned: this year by optimizing the six policies, tough fight seven games, seven strengthen security measures, the average concentration in urban areas and strive to fine particulate matter (PM2.5) fell 4 percent to ensure that the number of heavy pollution days significantly reduce atmospheric environmental quality improved significantly, people's happiness significantly enhanced blue sky.

3, increase economic policy support to accelerate clean winter heating work, in accordance with the principle of "Jiangyoufalie", the establishment of special funds for air pollution prevention and control arrangements with local ambient air quality to improve performance linkage mechanism.

1, lay the tough restructuring, according to the law closed down quit a number of energy consumption, environmental protection, safety, technology and production of non-compliance or substandard products out of production capacity, before the end of the year, the Guanzhong area basically completed "messy dirty" industrial enterprises and in accordance with regulations cluster comprehensive treatment.

2, tough fight industrial pollution control, focusing on gas-related industrial pollution sources to perform all the installation of flue gas emission standards new online monitoring facilities, the Guanzhong area cement, coke, iron and steel, nonferrous metals, glass, ceramics, tile and other industries, and to ban coal-fired hot air furnace, the coal-fired cogeneration substantially eliminated heating pipe network coverage heating, drying furnace (kiln).

4, clean energy alternatives tough fight, central heating station complete transformation of existing coal-fired clean off the area before the end of the city to clean the heating rate in urban areas off more than 90% before the end of May to complete the Guanzhong area rural village set loose coal governance indeed household inventory; motor vehicle pollution control tough fight, and increase freight railway construction investment, strengthen the construction of urban public transport system, promote high-emission motor vehicle pollution control, Guanzhong area cities and built-up area buses in the proportion of new energy vehicles to achieve 80 %, starting July 1, the province's implementation of six national emissions standards.

"Program" also pointed out that by strengthening the organizational leadership, strengthen environmental law enforcement, special inspectors carry out inspections of air pollution, strengthen grid environment supervision, improve environmental monitoring and control network, strengthen science and technology infrastructure support, strict accountability assessment 7 safeguards to ensure that work effectively.

By the flue gas is added to the combustion products within the combustion zone, not only lowers the combustion temperature, NOx formation is reduced; simultaneously added to the flue gas reduces the oxygen partial pressure, which will reduce oxygen and nitrogen generating process of thermal NOx, whereby reduce the formation of NOx. Depending on the application of the principles, applied in two ways flue gas recirculation, and internal recirculation of flue gas are recirculated to the external smoke. For external flue gas recirculation techniques, the flue gas from the outlet of the detailed information about traveling grate assembly in boiler via an external conduit, re-added to the furnace. According to the study, external flue gas recirculation can be reduced to 70% of NOx formation. The ratio of the outer loop NOx control effect has a greater impact, as the outer loop increases the proportion of NOx reduction rates are more obvious, but the electrical energy consumption for circulating air will also increase.

First, look at the regular detailed information about traveling grate assembly in boiler manufacturers

What is the impact of changes in steam pressure steam temperature? why? ? (1) When the vapor pressure is increased, the superheated steam temperature is increased; vapor pressure is lowered. Superheated steam temperature decreased. This is because when the vapor pressure increases with an increasing saturation temperature, from water into steam need to consume more calories in a case where the combustion amount becomes unchanged, since the pressure rises, to reduce the moment of evaporation detailed information about traveling grate assembly in boiler , by resulting in reduced amount of steam superheater, heat absorption is increased relative to the steam, resulting in superheated steam temperature rise, and vice versa. Dynamic process (2) just above phenomenon instantaneous change given operating pressure when the vapor pressure changes with stable steam temperature and steam pressure opposite to the above phenomenon.
