Three projects of this designs do some trials with set up on the early form , belief that a certain degree just come up to say hot electricity the power station design here the foundation , and can certainly design out the more reasonable project according to the actual circumstance request 本设计的三个方案在某种程度上来说只是热电联产电厂设计的雏形，相信在此基础上做一些尝试和创新，并根据实际情况要求一定能设计出更合理的方案。
Based on the analysis of the tangshan xinqu and qian an and gangyao thermoelectric power units , a model of real - time ordering power by heat on combined heat and power based on working chart is erected , a method of related generating electric power appraisement is set up , and the software of ordering power by heat on combined heat and power system is developed . based on delphi language and sql server database , the structure and functions of ordering power by heat on combined heat and power system are discussed , and a method of data processing is also put forward . the function of data storage and past data query and account report forms is achieved 为解决此问题，本文以唐山新区热电厂、迁安热电厂、缸窑热电厂的供热机组为例，根据其机组工况图建立机组“以热定电“运行的数学模型，并编制了相应的软件文中介绍了基于delphi语言与sqlserver数据库的软件结构功能与特点，软件可实时给出各参数和热电联产以热定电考核曲线，能够实现数据存储、历史数据查询、统计报表等多种功能，这对于电力管理部门合理地为热电厂下达发电指标，加强和完善对热电联产企业的管理，提供了理论依据和技术支持。
The differences between small - scale thermal power units and small - scale combined heat and power generating units are explained according to domestic energy policies . the advantages of co - production of heat and power are analyzed . the social and economic profits due to co - production of heat and power in the fields of energy saving , loss decreasing , environment protection and peak - valley power load regulation are discussed . the check index of thermal power plants is explained and advice on improving construction and operation of small - scale heating and power plants is suggested with consideration of domestic practice 依据我国的能源政策，阐述了小热电机组与小火电机组的区别；分析了热电联产的优越性；论述了热电联产在节能降耗、环境保护及电网调峰中产生的社会效益和经济效益，并结合我国的实际，对热电厂的考核指标进行了探讨，对改善小热电的建设与运行提出了建议。
The boilers are well - structured and bring good benefit for enviroment protection . china is a big country for energy consumption , now , saving energy and enviroment protection have been already put on the importment order of the day . the quantity of the boiler required for the development of industry has been increasing , the annual requirement is about 100 , 000steam - tons . recently , it has higher requirment to develop the thermoelectricity combustion production . therefore , 220ton hour circulation fluidized bed will have a good prospective market 中国是一个能源消耗大国，现已将节约能源和保护环境，提到了重要日程，而工业的发展对锅炉的需求量还在不断增大，每年约需10万蒸吨，且目前对发展热电联产有更高的要求，因此，生产220吨时循环流化床锅炉有较好的市场前景。
In order to win in the competition , each electricity producing enterprise has to strength the management of the whole production process and make good use of self potency , optimize its operation mechanism , as to reduce the waste . to develop thermal - electric cogeneration can use energy comprehensively and it is a effective method to achieve the goal above 当前，电力市场竞争机制已经引入，由于电力产品的同质性，成本竞争就成为主要的方式。这就要求各电力企业加强电力生产全过程的管理，深挖内部潜力，优化运行方式，减少生产过程中的重复、浪费。发展热电联产，实现能源的综合利用，就是有效的解决办法之一。
Actual runs prove that the construction of the heat and power co - production unit is an important route for medium and small nitrogenous fertilizer plants based on coal to thoroughly solve the problem of comprehensive utilization of slag from the gasifer and fine ash , turning these wastes into wealth , and the necessary choice for nitrogenous fertilizer plants to lower production cost , increase benefits and improve competitiveness of the plants on the market 实际运行情况证明，建设热电联产装里是以煤为原料的中、小氮肥企业彻底解决造气炉渣及细灰综合利用，使其变度为宝的一条重要途径，也是氮肥企业降低生产成本、增加效益、提高企业市场竞争力的必然选择。
The essence of this system is " cogeneration and one supply " , i . e . , on the one hand , the input of the energy system is fossil fuel , its productions are heat and cold , it has only one supply ; on the other hand , the process of produce is cogeneration , power is consumed by the cold and hot water unit as middle production , and the cold and hot water unit produces the heat and cold 这一系统的实质是“联产单供” 。也就是是说，这一能量系统的输入是化学燃料，目标产品是热量和冷量，是“单供”的；另一方面生产过程是热电联产的，电作为中间产物供给冷热水机组消耗掉，通过冷热水机组生产出热量和冷量。
This thesis assesses the investment project of 2 x 50 mw thermoelectricity cogeneration in tian fa company from the prospect of financial management . this assessment includes the whole process of marketing research , financing , investing and performance appraisal . thus we will have a comprehensive knowledge about analyzing the feasibility of one investment project , which is very important for a mba student 本论文从公司财务管理的角度出发，应用案例分析的方法，就笔者所在单位? ?天发公司2 50mw热电联产投资项目，从市场调研、融资、投资到投资回报率进行全过程剖析，使我们对一个项目投资可行性的分析和评价程序能有一个全面的了解，这对一个mba而言恰恰是非常必要和关键的。
The proportion of natural gas in consumption of energy is constantly rising . gas turbine and engine cogeneration is one of the rational ways in utilization of natural gas . using index system evaluating thermodynamic performance of energy utilization systems on the basis of electricity , the allocation models of the fuel consumption for the gas turbine and engine chp plant were deduced 本文根据以电量为基准的热力性能评价思想，研究燃机热电联产煤耗分摊问题，并给出了燃机燃气蒸汽联合循环热电联产、燃机简单循环热电联产系统的电、热两种产品生产的煤耗分摊模型。
