boiler manufacturers punjab haryana
How to determine the steam boiler manufacturers punjab haryana plant accident occurred less water? When the water level is less than the minimum water level has been defined, but the water can still be seen in the gauge water level, slightly less water is determined; when the water level can not see the water meter, it is judged severe water shortages. Status summarized in the following: a conventional water level (1) is less than the height of drum level defined; (2) low level alarm, automatic warning sounds, warning light flash from; (3) superheating steam temperature increases; (4) Enter water is not a conventional, inferior steam flow rate value; (5) the flue gas discharge temperature.
Boiler overhaul wineries which note brewery boiler manufacturers punjab haryana after running for some time, is inevitable to carry out a series of maintenance work, maintenance, etc., then what exactly is the problem the details need to pay attention when performing such work? Here small taping simple to understand. (1) In the process of maintenance, the maintenance work to have the support of the operating environment and conditions, if there is a lack of conditions should be specific conditions, to create a feasibility conditions. Before (2) Maintenance start, try to ensure that the boiler is in shutdown state, but without water, electricity, etc., in order to avoid the repair process, the occurrence of unnecessary accidents. (3) during repair, maintenance tools should regulate different place, count the number of use, so as to avoid errors by the operator, the tool is not left in the furnace or other suitable place. (4) after the repair work, be sure to carefully inspect the site, if necessary, simple operation and commissioning, to ensure that after a brief qualified operating personnel before leaving the venue. (5) The last point is that after the repair work, in addition to timely and truthfully report to their superiors, but also to make a record, learning, review, to ensure zero-error process can be done in accordance with a more standard process in the next maintenance work preferred state. In short, boiler maintenance and repair will directly affect the life of the boiler, the use of safety, efficiency, and normal operation of the equipment and so on, so be sure to regulate the operation.
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 manufacturers punjab haryana 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.
Extend the life of the boiler manufacturers punjab haryana maintenance shutdown (boiler) 1. Within the boiler water off after the shutdown, open for all internal inspection hole hand hole corroded, remove the pot shell and silt debris collection box. 2. Clear fouling heated surface to enhance heat transfer, reduce heat resistance. 3. Check hearth furnace wall, the repair of damaged insulation, air leaks to eliminate smoke leakage. 4. Check each boiler drain valve switch is flexible, the sealing situation is good. The wet boiler maintenance: After pot scale, rust and other cleared, by injection into the boiler supply pump is full softening, oxygen qualified demineralized water, and adding an alkaline solution, the oxygen with the metal surface of the pot water inert to the reaction, the metal from corrosion. Before dosing, and closing the relevant check valve to prevent leakage into the operating system alkaline solution, while preventing leakage of water into the pan operation of the system, so alkaline concentration.
