本文对三种炉型的比较，得出优选燃气锅炉的结论。有效地保护环境，要防止边治理污染边制造污染。锅炉烟气是主要的大气污染源之一，因此我国环境保护局和国家技术监督局于1992年5月发布了《锅炉大气污染物排放标准》（GB13271-91），该标准对原始含尘浓度，锅炉烟尘允许排放浓度及SOX，NOX最高允许排放浓度，分别根据一、二、三类地区对环境保护的不同要求做了详细明确的说明和规定。 燃油锅炉虽然在烟尘排放大大低于燃煤锅炉，但燃油锅炉SOX和NOX排放量却远远高于燃气锅炉。人们在比较燃煤和燃油锅炉时往往忽略了燃油锅炉的SOX和NOX，等到酸雨成灾再考虑脱硫时已晚矣。 所以客观地说，燃气锅炉无论是从环保角度还是从能源利用角度来说都是较为理想的，这主要是由于气体燃料比固体、液体燃料更易充分燃烧，燃烧热效率更高。 2.3 锅炉的设置费用 用户在设置锅炉房时必须考虑锅炉房锅炉设置的经济性，从而使所选用的锅炉既满足上述要求又节省投资费用，主要从以下几个方面考虑： ①锅炉设备费用（机组）； ②为满足锅炉正常运行的配套辅机费用； ③为放置上述设备的土地征用费； ④锅炉房土建投资费用及其他相关费用。

JILRuntime A general purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. Objects and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for embedded systems where a small memory footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, general purpose programming environment.

This toolbox distributes processes over matlab workers available over the intranet/internet (SPMD or MPMD parallel model). It is very useful for corsely granular parallelization problems and in the precesence of a distributed and heterogeneus computer enviroment. No need for configuration files ! Cross platforms, cross OS and cross MATLAB versions. Workers can be added to the parallel computation even if it has started. No need of a common file system, all comms are using tcpip connections

CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS. the newest version, support windows.
