consisting waste heat to steam heat recovery boiler

Third, the safety and reliability and environmental impact

A, commercial condensing gas boiler

2019, Nanjing for more stringent ozone pollution, for volatile organic compounds, governance and control measures nitrogen oxides unabated.

Nanjing Ecological Environment Agency staff members at atmospheric introduction, with the recent temperature increases, there has been a trend in some parts of ozone exceeded. This summer, the environmental protection department will introduce stricter air pollution control measures, starting from the two aspects of governance volatile organic compounds and nitrogen oxides to reduce ozone pollution.

It is understood that Nanjing will be completed this year 44 companies VOCs governance and thermal power, cement, bricks and other building materials industries fugitive emissions-depth treatment in the city in batches with a gas-fired boiler 936 units, the implementation of the nitrogen oxides governance Sector Engineering; city station 475 to achieve ultra-low emission particulate biomass boilers, for the privately polluting fuels blended biomass boilers embodiment eliminated. It is worth mentioning that the revised "Nanjing Atmospheric Pollution Prevention Act," to be implemented next month. Among them, organic solvents, paints use, as well as volatile organic compounds corporate governance and management have put forward new demands.

Boilers help you analyze what is the activity analysis for consisting waste heat to steam heat recovery boiler tell you what the meter event analysis? What is the role of activity analysis instrument? Operation of boiler operation when, through a variety of instruments to reflect the instructions. , Analytical instruments activity is the analysis of boiler operating conditions are normal operating according to the instructions of the instrument data and trends. In the normal operating parameters of the boiler from a variety of thermal monitoring instruments to measure various parts of the vehicle data include pressure, temperature, flow, level, current. In normal operation, by monitoring the operating parameters, to analyze the health of passers is determined, when an accident occurs, the site may be analyzed and the nature of the accident is determined by the abnormality data changes, in time to create conditions for the accident. Induced draft fan surge is due to the import and export of its vanes differential is too large to happen. Importers vanes which by its resistance and a differential pressure of pipeline, more likely to occur when a large surge of static vane duct fan same primers resistance test analysis. Induced draft fan vane opening force generated when the respective constant pressure and flow rate, the pressure generated when the fan and greater than or equal flow resistance and Smoke conduit, the fan will not be able to work stably surge occurs. Flue Gas pipe while the resistance increases, the outlet pressure of the fan flow rate can not overcome the backflow resistance of the piping system occurs. When the flue gas back to the duct fan outlet pressure resistance is reduced, and flue gas downstream out. Flue gas flow back and forth so called surge. Therefore, when a large wind smoke pipe resistance because of the opportunity when the wind is not more likely to contribute to the surge occurred. Analyze the start, stop impact pulverizing system for boiler combustion conditions. Since the tertiary air with powder, start / stop-milling system, furnace fuel amount relative increasing / decreasing the amount of oxygen is relatively increased / decreased. Milling boiler system startup long flame length is long, good fire fullness, and vice versa; low load operation or a multi-pulverizing system full stop milling system, in particular to prevent the flame from extinguishing occurs suddenly.

(1) Low NOx combustion technology, which controls the combustion process in the generation of nitrogen oxides, mainly for large coal-fired consisting waste heat to steam heat recovery boilers; low NOX combustion technology can reduce 30 ~ 50% NOX emission values, to further reduce NOX in emissions, flue gas denitrification technology must be used.
