united arab emirates dual fuel fired steam boiler

(3) According to the boiler technical standards: strictly control the normal water level of the boiler to prevent the steam from being watered due to the high water level, resulting in deterioration of steam quality. In addition, avoid sudden increase or decrease of load, so as to avoid the occurrence of false water level, causing a sharp increase in water level and serious deterioration of steam quality.

What forms of chemical plant boiler inspection there? What forms of chemical plant boiler inspection there? Or organic heat boiler uses water as the medium pressure vessel was heated by a flame or electric heating, and multi-output heat to steam, hot water forms, during operation of boiler, the furnace member at a high temperature and pressure, or external temperature flame radiation, may occur wear, corrosion, distortion, scaling, and other defects over-burning, ash plugging may also occur, slagging phenomenon. More serious will lead to burst pipes or explosion and other accidents, if not timely detection to eliminate them, will eventually lead to loss of life, damage to equipment, to bring social unrest, cause losses to the state and enterprises. Check the boiler is a boiler to minimize the risk of the task. Boiler Inspection generally divided into boilers and boiler Supervision, Inspection and periodic inspection, the former is an integral part of the normal operation of the boiler in a test, divided into internal and external inspection test boiler boiler; the latter is mainly for boiler installation, alteration, major repairs an extremely important test carried out. 1, chemical plant boiler regularly inspect boilers periodic inspection refers to the periodic inspection of boiler inspection rules for safety and energy savings boilers carried out according to regular inspection prolong the service life of the boiler, including external inspection running under the boiler, boiler stop internal inspection and hydrostatic test under the operational state. External inspection cycle once a year; internal inspection period is every two years; the boiler because of structural reasons can not carry on in the inspection, hydrostatic test should be carried out, for the period of 3 years. Including internal content inspection for cracks, cracks, corrosion, scaling and other defects on the drum, boiler shell, superheater, airway pressure receiving member and the like; the same shall be the time when the problem occurs in the last test specimen methods for review. External inspection tests generally include the following elements: operation of the boiler external environment and load-bearing device, an external boiler piping, safety accessories and safety devices, auxiliary equipment. For external examination of organic heat carrier boiler, acidity should review inspection reports and records, kinematic viscosity, carbon residue, water and other indicators of compliance with national standards, to check its compliance with safety devices regularly boiler inspection rules. 2, Boiler Inspection Boiler Inspection supervision include chemical manufacturing supervision and inspection of boiler and boiler installation, alteration and major repair of supervision and inspection. Supervision and inspection methods commonly used data review, physical inspection and on-site supervision methods. When data review should be strictly regulated in accordance with the pot; when the inspection site monitoring, supervisory inspector should be carried out in accordance with the relevant system standards, to comply with the relevant safety specifications; when physical examination, in general, checks manner. Supervision and inspection of the boiler by the degree of impact on the safety performance of the boiler can be divided into A, B, C categories, followed by a significant impact, greater impact, the general impact. Former chemical plant boiler supervision and inspection, the following should be inspected units do a good job, ready to license within the validity period (but without permission or license application has been accepted); develop plans to submit construction plans or production supervisory agency; provided the necessary supervisory inspection work conditions.

Second Session of the CPPCC National Committee Session of March 5 press conference held in the afternoon, the CPPCC National Committee of Population, Resources and Environment Committee, Democratic National Construction Association Central Committee, Environmental Management Division of the Ministry of Ecology Environment Atmospheric Liu Bingjiang said: Last year, resolve more than 30 million tons of steel production capacity, 810 million kilowatts of coal-fired units basically reached the national emission levels of natural gas, built the world's largest clean coal power base, out of 1.3 million units in industrial furnaces, coal accounts for the country's primary energy consumption the proportion of first time below the 60% to 59%, and turned off the small coal-fired boilers 23000 units.

At present the country has completed a preliminary air pollution control goals, the future will continue to promote coal-fired boilers governance, and the introduction of more stringent emission performance standards of air pollution.

3.The boiler shall realize efficient desulfurating, low temperature combustion, and low discharge of nitrogen oxide.

4.With a high speed, the load can be adjusted in a wide range.

5.By comparison with pulverized coal fired industrial boiler, the fuel preprocessing system is simple, which is easy to implement comprehensive utilization of ash.
