蒸汽锅炉

If the boiler don't close the check valve, then must prevent back flowing to the boiler, valve clack mould weight and buffering piston can seal under gravity action, they make steam and condensed water can't flow back to the boiler under the low air pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

With the affects of tgravity, the valve clack and damper piston can get sealed immediately that steam and condensed water won't refluence to the boiler even in an atomosphere of low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

Converter steam can be fully used via increasing the running pressure of boiler, enlarging accumulating capacity, bring converter's boiler to play double function, improving steam quality, steadying steam pressure for RH and so on.

通过采取提高余热锅炉运行压力、增大蓄热容积、转炉汽化装置"一机两用"、改善蒸汽品质、恒定供真空泵的蒸汽压力等措施，转炉蒸汽能够充分得以利用。

"In steam systems, steam is generated in the boiler and led to radiator s through pipes."

在蒸汽系统中，由锅炉产生蒸汽，经由管道将蒸汽导入散热器。

在蒸汽系统中，由锅炉产生蒸汽，经由管道将蒸汽导入散热器。

First,the paper introduce the automation summarizer of marine boiler and the basic principle of PLC(SIEMENS PLC S7-200 of Germany). Following, the paper introduce a typical boiler system of shipping. On this base, the paper pay more attention to making control programme of S7-200 for oil auxiliary boiler.

文章首先介绍了船舶辅助锅炉自动控制的总体概述和可编程控制器（德国西门子可编程控制器S7-200）的基本工作原理，详细介绍了船舶燃油辅助锅炉的典型系统，在此基础上，着重对采用S7-200控制的燃油辅助锅炉进行了PLC编程，其中对蒸汽压力采用多位控制。

A new leak supervision over waste boiler is introduced. Waste heat boiler gas phase, i.e., content change of non condensable gas and dissolved gas is determined to judge the leak status of waste heat boiler.

介绍了一种废热锅炉漏点监控新方法：在生产系统不停车的情况下，通过测定废热锅炉气相即蒸汽中不凝性气体和溶解性气体的含量变化趋势来判定废热锅炉泄漏状况。

If the boiler check valve hasn't be shut, then must prevent steam and water back to the boiler . With the effect of tgravity, check valve and damper piston can immediately get airproof and the steam and water won't back to the boiler even in an atomosphere of low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

The statistics of oil field production indicates that the dryness fraction of the steam heat boiler export is about 75% at present .While the dryness fraction of steam of the steamed well mouth is only about 60%, which affects the effect of steam huff and puff and the economy of thermal production.

油田生产统计情况表明，目前热注锅炉出口蒸汽干度一般在75%，而注汽井的井口蒸汽干度仅为60%左右，影响了蒸汽吞吐效果和热采的经济性。

Started the research of gas-turbine HRSG in the 1970s, the company has developed horizontal and vertical type HRSG, and has the ability to design and fabricate 23~400MW HRSG for gas-steam combined cycle gas-turbine. Such HRSGs can be single-pressure, double-pressure, or triple-pressure, and the circulation can be natural type or forced type. By the end of May 2007, the company has sold 144 sets of gas-turbine HRSG, with the domestic market share of more than 80%.

公司从上世纪七十年代后期开始研究、开发燃气轮机余热锅炉，坚持引进消化吸收和自主开发并重，至今已开发有卧式和立式两种技术、可设计制造单套装机容量23－400MW燃气蒸汽联合循环的各类单压/双压/三压自然循环、强制循环燃气轮机余热锅炉，截止07年5月公司共销售、生产燃汽轮机余热锅炉144套，国内市场占有率达80%以上。
