汽轮机驱动锅炉引风机的兴起
发布者:admin  日期:2016-05-18  点击:1265

  由于引风机汽轮机无经验可借鉴,电厂与设计院在方案设计和设备选型过程中非常谨慎。一方面,引风机属于锅炉辅机,烟风系统在运行中存在很多不确定性。另一方面,选型结果会直接关系投标价格,影响产品的市场竞争力。从汽轮机内效率、产品成本、机型今后的通用性、机型所需的最短制造周期多方考虑,股份公司对选型结果反复讨论,力求机型最具市场竞争力。

Due to the wind turbinewithout experience can be used for reference, the power plant and DesignInstitute in the design and equipment selection process is very cautious. Onthe one hand, belonging to the auxiliary boiler fan, smoke ventilation systemhas a lot of uncertainty in the operation. On the other hand, the selectionresults will be directly related to the tender price, the impact of productmarket competitiveness. From the efficiency of the turbine, product cost, thefuture versatility of the model, the most short manufacturing cycle needs toconsider the most short manufacturing cycle, the joint stock company on theresults of repeated discussions, and strive to model the most competitive.

 

在经历了海门电厂、沁北电厂、北仑电厂三个项目的招投标、签约、装置资料的交付过程后,股份公司形成了NKHNG两大系列、3个典型机型。现在全国100万吨级的引风机有80台仍在使用电机拖动,60万吨级的有500台仍用电机拖动,海门电厂等三个引风机汽轮机项目,为国内大型火电采用汽轮机驱动锅炉引风机打开了新的市场空间。

In experienced in HaimenPower Plant, Qinbei Power Plant, Beilun power plant project bidding, contract,device data delivery process, shares of the company formed NK, HNG two series,three typical models. Now national 100 million ton of induced draft fan with 80still in use motor drive, 60 million ton have 500 units are still using motordrive, Haimen Power Plant and other three draught fan turbine project, fordomestic large thermal power by use of steam turbine driven boiler induceddraft fan opened the new market space.

 

  在海门电厂采用汽动引风机以前,火力发电厂锅炉引风机均采用电动机驱动方式。随着近年来电力行业装机规模日益扩大,中国火力发电厂运行负荷长期偏低,煤价的攀升又进一步导致发电厂经济效益下滑。在国家节能减排政策背景下,各大电力公司纷纷采取节能降耗措施。引风机能否采用汽轮机驱动成为国内各大电力公司和设计院关注的焦点。

Used in Haimen Power PlantSteam fan, coal-fired power plant boiler(www.rguolu.com) fan adopts the motor drive mode. As inrecent years the power industry installed scale expands day by day, thelong-term low load operation of China'scoal-fired power plants, coal prices rise further lead to decline in the economicefficiency of power plant. Under the background of the national energyconservation and emission reduction policy, the major power companies havetaken measures to reduce energy consumption. Whether or not the draught fan canbe driven by steam turbine has become the focus of the major power companiesand design institutes in China.
