steam generator with temperature adjustable
Expected by the end of this year, Jiangsu Province, the province will complete the ultra-low emissions below 100,000 kilowatts coal-fired units. It's Jiangsu Province, following more than 100,000 kilowatts ultra-low emission coal-fired units in 2017 renovation, energy-saving and environmentally friendly coal a "first in the country."
According to statistics, Jiangsu Province in energy consumption, accounting for over 60% of coal, which accounts for coal and coal consumption sticking. Industrial emissions of air pollution is the bulk, ultra-low emission power plants, clean coal is to enhance efficiency, promote air pollution control "top priority."
According to the deputy director of Jiangsu Provincial Development and Reform Commission Energy Bureau, Jiangsu Province coal units in the national energy conservation program first started, the fastest progress. In the coal transformation "mentioned standard extended surface" advancing, Jiangsu Province by the national requirements of more than 300,000 kilowatts stand-alone, single expanded to more than 100,000 kilowatts, 100,000 kilowatts this year covering the following units. In order to promote energy saving coal-fired power plant, Jiangsu Province, also the first start price subsidies, together with local award and subsidy, enterprise since the vote, five years invested a total of 23.4 billion yuan.
Price subsidies coupled with strict control of environmental protection, promote the province of large-scale coal-fired power plants, clean production. By the end of last year, Jiangsu Province, a total of 225 sets of 73.6 million kilowatts coal units to complete the environmental transformation. Combined with the transformation of coal to the end of last year, out of sync, Jiangsu Province, small thermal power units 2.95 million kilowatts.
Coal transformation of wide coverage, high standards, emissions dropped significantly. Emissions of coal dust, sulfur dioxide and nitrogen oxides three major pollutants, Jiangsu line monitoring mean values of 2.3 mg / cubic meter, 18.5 mg / cubic meter and 35.5 mg / cubic meter, effective domestic optimal. Transformation, Jiangsu Province, to proceed with flue gas heat recovery, central heating, shutting down small thermal power, 25.7 million tons of standard coal last year to save.
Significantly reduce the amount of coal emissions at the same time, the province "Blue Sky index" every year. According to the Provincial Department of environment statistics, since 2013, the province PM2.5年均浓度连续 six years continued to decline, good days than from 60.3% in 2013, rising to 68% last year.
In case of Guddu power station, which is characterised with supply of natural gas from the nearby Mari and Kandhkot gas-fields, all existing equipment (turbine, boiler and generator) will be replaced. Existing boilers will be replaced with 1x300MW supercritical steam generator with temperature adjustable.
What is the role of energy saving boilers and boiler smoke box: to learn and understand the boiler, the following will be continued, because it is the site of important products, therefore, the need to have a serious learning. And this for us, but also beneficial and harmless, at least, be able to increase expertise on the boiler, and at the same time, can also achieve the proper use of the product, to obtain good economic benefits. 1. What is the energy saving boiler? Energy saving boiler, which is a particular kind of a boiler, specifically, it is the gas generator and boiler combined into one, it is put into the fuel from the grate stoker opening to the combustion, thereby making water vapor phase with seam combined. And, by actively generating a high temperature flame burning system, and further, burned at sufficiently high temperature, to obtain a good combustion.
1. The pressure test the electrical components of the electrical steam generator with temperature adjustable if the steam generator is completely assembled (i.e., as good as the boiler and the header connecting pipe, tube, heating the surface of the assembly line and the like). Header pressure test and assembly line can not, if they have been made in the component parts and hydraulic test or an ultrasound test of 100%, or other non-invasive test similar words. Upon completion of the processing of these components assembled, pressure is applied to test weld inspection no damage (radiation or ultrasound) to the full-length flaw detection. 2. All of the tubes, welded, cast, shaped parts and components, not all of the processing done in the hydrostatic test steel. Said component members of the hydrostatic test is not necessary, if they have done 100% ultrasonic testing or other similar NDT inspection. Superheater and economizer; while allowing the individual parts and components subjected to the hydraulic test in combination together with the electric boiler, not separate discrete electrical steam generator installation if reprocessing or hydrostatic test words. Included in the scope of the hydrostatic test all of the electrical steam generator, superheater, economizer, steam generation and processing power of the finished part. After working on the fixed plant boiler, is delivered to the sub-mounting parts, components, assemblies dispersion transportation, so the installation must be pressure test. Hydrostatic test purpose is to check electrical steam generator, superheater, economizer all density and strength member, all other members must also be welded hydrostatic test.
