Importance Of Boiler Feed Water Treatment

Precautions gas importance of boiler feed water treatment ignition 1, for gas-fired boilers, the time is not on fire, then it must purge the furnace flue and then only after a second firing. 2, in order to prevent a gas explosion, gas boilers require not only before the start of the boiler furnace and flue gas purging channel, and the need for a purge gas supply pipes. The gas supply duct purge medium is typically an inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace flue with a certain flow rate is the flow rate of air as the purging medium. Case 3, in the rear of the boiler did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case. 4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, exhaust components must be detected in order to determine the excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.5 , fireman switch should always pay attention to the case of the gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valve, the normal operation may be started up. 6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion. 7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close the vent valve. 8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, it is timely contact with the gas company, gas pressure if there is a change. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter. 9, should comply with boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. There are exceptions, when not solve the problem, depending on the nature of the problem should promptly contact the boiler plant or gas company, to conduct maintenance by a professional maintenance staff. 10, shall comply with the relevant national gas. Not free to fire the boiler room, prohibited welding, gas welding and other operations in the gas pipe roadside.

Working Principle of coal fired boilers

Recently, Hebei Province issued the Notice on governance oxides of nitrogen gas importance of boiler feed water treatment.

It reads as follows:

Municipalities (including Dingzhou, Xinji) people's government, security male New Area Administrative Committee:

In order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, win the Battle of the sky, it now follows nitrogen oxide gas boiler notice governance:

First, we attach great importance to understand the situation, do a solid job governance

Nitrogen oxide gas boiler control, is to win the Battle of the sky, to promote an important measure to further improve the quality of atmospheric environment, is to deepen the air pollution control efforts around one main direction, is an important part of governance to deepen the boiler, the province's existing gas 10,790 tons of steam boiler units 37318, 23838 9,932 tons of steam wherein steam 10 tons / hr or less and a gas boiler, substantially free of nitrogen oxides into the process, the nitrogen oxide emissions of about 38,500 tons, the average concentration of about 150mg / m³.

Meanwhile, the province average concentration of nitrogen oxides is high, annual average concentration of nitrogen oxides is much lower than the rate of decrease of sulfur dioxide, haze is generated, among the major causes of the high ozone concentration.

Beijing and Tianjin to the surrounding gas on boiler control arrangements, and achieved initial success, Beijing completed the transformation of low - NOx combustion gas, nitrogen oxide emissions concentrations within 30mg / m³, the total emission reduction of 80%; Tianjin local emission standards promulgated boiler air pollutants, nitrogen oxide emissions concentrations within 80mg / m³.

Localities must deepen understanding, with a strong sense of political responsibility and the courage to act in the spirit of reinforcing initiatives, compaction responsibility to carefully organize governance, and make new contributions for winning the Battle of the blue sky.

Second, focused, clear goals, and win the battle governance

All localities should strengthen awareness of time, reasonable arrangements to ensure on schedule to complete the task, to the end of June 2020, the existing non-electric gas steam boilers, hot water boilers, Stoker stoker furnace and completed the transformation of low-nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³, 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler to install air pollution automatic monitoring facilities and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to install the nitrogen oxide gas boiler exhaust gas analyzer, a field inspection data should be able to provide emission monitoring at least one year.

Before the end of October 2018, more than 10 municipalities should be completed tons of steam boiler low NOx combustion gas transformation stations 383 11 399 tons of steam, before the end of October 2019 completed two-thirds of the total number of units, low nitrogen completed the task of transformation before the end of June 2020 . Please cities combined with the results of the investigation, fill out the "low NOx combustion gas boiler Hebei transformation time schedule", determined by boiler transformation completion time, on or before July 10 will stamp paper and electronic versions simultaneously submitted to the provincial environmental protection hall.

Third, strengthen safeguards, unique strict examination to ensure good results

(A) strengthen the organization and leadership. Provincial Office of atmospheric nitrogen oxides governance into the gas-fired boiler air pollution control evaluation system, the implementation of scheduling monthly reporting system to carry out supervision and inspection, sum up experience, solve problems and promote the implementation of the objectives and tasks. To pay enough attention to promote ineffective, behind schedule reprimand, interviews and even administrative accountability. For failure to complete the task of transformation on schedule, annual nitrogen oxide concentration in excess of the provincial Department of Environmental Protection will suspend approval of the EIA nitrogen oxides new construction project documents in addition to the people's livelihood projects. Localities should also strengthen organizational leadership, the implementation of the task to the responsible units and responsible job, strict accountability assessment.

(B) increase policy support. Formulated "Boiler Air Pollutants Emission Standards Hebei Province," received strict emission limits of pollutants. Governance throughout the project through acceptance of appropriate subsidies in integrated financial subsidies to control air pollution. Simplify the EIA approval process, gas boiler combustion of low nitrogen transformation refer to "construction project environmental impact assessment of Classification Catalog (2017 version)," projects related to the registration form online record management.

(C) to strengthen law enforcement and inspection. All localities should follow a comprehensive air pollution control requirements, supervision and law enforcement to carry out special checks on overdue fulfill the task be ordered to stop production of governance, strengthen the daily supervision of completed projects to ensure stable discharge standards. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.

(Iv) strengthening quality management. Municipalities and counties should strengthen the technical capacity of equipment manufacturers, project progress, acceptance monitoring, supervision and management of funds, select the technology is mature, with good results, there are success stories of the equipment manufacturers. Strengthen social management of the testing organization, supervision and tissue sampling tests and test results to ensure project quality.

For a long time, Hebei Province as the country's most polluted regions, gray haze is normal people's lives. Hebei Province, north of Yanshan, west of Taihang Mountains, was a famous country poised; but in recent years, due to the production process to run some heavy steel mills, cement plants, thermal power plants and other chemical companies, emit large quantities of harmful substances into the air, Over time, the increasingly serious air pollution, haze follow.

The notification transformation of low nitrogen gas boiler, the boiler will be put on nitrogen means lower environmental protection, and promote air governance, Hebei Province, to realize the dream of the blue sky.
