remove limescale from water boiler

The greatest part of the current heat demand of the oil refinery is provided by direct heating in process furnaces and by steam that is produced in steam boilers. Steam is the main utility at the refinery site. In the fractionation columns, as well as in many heat exchangers, steam is used as a heat source, and the condensate can be recovered and reused. In other units, such as strippers, it is injected to improve the process. And the steam headers are connected by let-down valves and turbines, the latter used in direct drive configuration to operate compressors and pumps.

Recently, the Hebei Langfang municipal government office "ten policy measures to support Hebei Province to promote the transformation of key industries and Ultra Low Emission Boiler (depth control)," according formulated and issued a "Langfang City to promote the transformation of key industries and Ultra Low Emission Boiler (depth governance) policy measures to support ten "(the" measures "), and comprehensively promote the iron and steel, cement, glass and other key industries and the transformation of ultra-low emissions of pollutants boiler, boiler-fired power plant pollutants depth governance.

"Measures" mentioned, strictly implement the "smooth approval of the green channel" to further deepen innovation and entrepreneurship, service development, people's livelihood-oriented "double hit double service" activities, enhance the quality and speed double simplify the above key industries and boilers the transformation of ultra-low approval procedures ultra-low emissions of air pollutants and other projects, the implementation of government-supported environmental protection equipment investment tax credit policy.

To carry out the EIA approval, pollution permits, environmental supervision and law enforcement services double forward, promote cleaner production, guide enterprises to upgrade pollution control facilities, strengthen fine management, promote the production of green, clean; to give priority to conduct emissions trading . Start as soon as the secondary market trading emission rights, to carry out the depth of emissions of air pollutants and ultra-low emissions of coal-fired power plant transformation iron and steel, cement, glass and other enterprises, boilers and emission reduction projects, the formation of sulfur dioxide, nitrogen oxides emissions amount, priority emissions trading, emission reduction achieved early, early benefit, large reduction, big benefit; promote emission right mortgage loan; to recommend inclusion of advanced technology directory; the implementation of differential pricing policy; to implement load shifting production of differentiated management , in accordance with provincial requirements for stability and achieve ultra-low emissions standards acceptance iron and steel, cement, glass and other enterprises and boilers, as well as in-depth treatment and complete acceptance by coal-fired plants, the implementation of green scheduling, in accordance with the relevant policy requirements appropriate to reduce or avoid peak load shifting production to heating season; to support the selection of units involved in green, continued to improve air quality, and resolutely fight win battle of blue sky.

What is a thermal power station boiler? Does the normal pressure boiler need annual inspection? Thermal power station boilers, commonly used in power plants for power generation and heating boilers. Moreover, the capacity of this kind of boiler is relatively large, and the main unit is usually 300 MW. Normal pressure boiler this kind of boiler, it is for the general container and not belong to the pressure vessel, therefore, does not need to carry on the annual inspection.

Condensing steam boiler worth the user to select three reasons advanced heat transfer technology, fuel combustion, low emissions of nitrogen oxides ...... condensing steam boiler with its obvious technical advantages in many hearts and minds of business users. Condensing steam boiler thermal wear because of the major characteristics of the boiler itself and products stand out, it is becoming a public company recognized and selected mainstream boiler. Here follow the fast boiler together, to understand why users choose to use the steam condensing boilers better. 1, easy maintenance overhaul internal boiler set up more than 10 monitoring probes, water pressure, water temperature, power supply and other parts have made a key protection, and intelligent control room connected to the probe, once the site of abnormal or failure to monitor the problem, immediately activation of the alarm, timely remind the operator to check the status of the boiler. For joints and other mechanisms to protect the relatively weak position, also set up manholes and hand holes for easy inspection and maintenance technicians later. 2, intelligent user interface condensing steam boiler start-up and adjustment is through the intelligent touch-screen direct operation, clear user interface resolution, Chinese characters makes clear, the entire boiler operating status are clearly show, including flame boiler temperature changes and changes in the state level and the like. 3, rational design SCIENCES condensed steam boiler is able to have good thermal efficiency, high-temperature steam can be permanently output, mainly due to the structure of a scientific and rational design. For example, a tail is provided in the flue economizer and a condenser, not only can improve the thermal efficiency of the boiler (more than 105%); also reduces exhaust gas temperature (220 deg.] C or less reduced from 100 ℃). Excellent quality considerable thickness (28mm) of the panel ND steel material, filling the gap between the centrifugal glass wool, have a good seal to protect the boiler and the insulation properties during use in a great extent. The reason why users are keen to be seen using a condensing steam boilers, mainly due to the obvious edge, not only because of the full range of condensing steam boiler technology to improve the performance of outstanding features, energy saving and pollution-free and does occur in the use and supply sufficient heat, and in the whole repair and maintenance of equipment is very convenient, the fast will be able to deal with the problem by past record.
