ABSTRACT In this thesis, the practical numerical simulation methods for the heat transter in the pulverized-coal fired furnaces of large boilers were studied.

本文对适宜于工程应用的大型煤粉锅炉炉膛传热工程化数值模拟方法进行了深入研究。

The company was founded in 1996, the use of local mineral resources, in a unique operating mechanism and standardize the management of the rapid development of the 2002 and 2005, twice extended technical regulations, is equipped with five-effect forced circulation vacuum evaporation system, automatic packaging production line, the most advanced instrumentation to monitor flow of two-cycle 1500 kilowatts-bed boiler and back pressure turbine-generator unit, the realization of CHP, with domestic advanced technology, to achieve an annual output of 200,000 tons.

公司始创于1996年，利用本地矿产资源优势，在独具特色的运行机制和规范管理下迅猛发展，通过2002年和2005年两次技改扩规，配有五效强制循环真空蒸发系统、自动包装生产线、最先进的仪表监控双循环流化床锅炉和1500千瓦背压式汽轮发电机组，实现热电联产，具有国内先进技术水平，年产达到20万吨。

The influences of SOFA on NOx emission and unburned carbon in fly ash were experimentally studied.

研究了SOFA对锅炉NOx排放和飞灰可燃物的影响规律。

Unburned carbon content in the fly ash is a main factor that has great impacts on the boiler efficiency.

1引言飞灰含碳量是影响锅炉热效率的一个重要指标，高含碳量影响了飞灰在水泥工业中的应用，导致处理困难和高昂的费用。

It is well known that the unburned carbon content in fly ash in a coal fired circulating fluidized bed boiler has been a major problem.

人们已经认识到飞灰含碳量是燃煤循环流化床锅炉的重要问题。

How ever ,careful thought must be given when making boiler selections for underfloor heating system ,as not all unit are compatible.

但是为地暖系统选择锅炉的时候必须注意并不是所有的设备都适合。

Modern high efficiency condensing boilers are ideal for underfloor heating as the low water temperature allow the boiler to work in condensing mode for most of the time ,thus increasing the efficiency even further .

现代的高效的冷凝锅炉对于地板采暖这种低水温的系统是个理想的选择，他可以在冷凝的模式下长期运行，因此效率就进一步增加了。

According to thermodynamic basic theory, the expression of the gas turbine circulation thermal efficiency to coupling parameter on the premise of considering actual influence factor and the matrix form of steam turbine thermal efficiency with the unfired HRSG is strictly deduced through mathematics method .

根据热力学的基本理论，通过严格的数学推导，分别推导出考虑实际影响因素的燃气轮机实际循环热效率关于耦合参数的关系式，非补燃式余热锅炉型蒸汽轮机热效率的矩阵形式的关系式，最后得出了燃气-蒸汽联合循环热效率关于耦合参数的关系式。

In this paper the dynamic mathematical model of CFB boiler was established and the dynamic performance under variation of different parameters was simulated.

文中对其建立了动态数学模型，仿真了在参数变动下锅炉的动态特性。

C. warm pump High-temperature liquid transfer pump such as the power plant boiler feed pumps must be warm before you start pumping.

c。暖泵事纪高温液体的泵，如电厂的锅炉给水泵，在启动前必须先暖泵。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
