They can be heated using a variety of different methods such as electric,gas,coal or fuel oil.<br /> <br /> *Commonly alot of&nbsp; boilers used for heating large areas such as Schools,Hospitals etc...are fired&nbsp; with low pressure gas. The actual pressure is less than 1 PSI.<br /> <br /> <strong>There Are Three Types Of Boilers</strong><br /> <br /> 1.Water Tube.&nbsp;Hot combustion gases pass through the tubes (fire inside the tubes) with steam or water outside the tubes.<br /> <br /> 2.Cast Iron Sectionals. Individual sections that are hollow, designed to contain the water or steam,<br /> and are interconnected. The hot combustion gases pass through and around the sections.<br /> <br /> 3.Fire Tube. The hot combustion gases pass through the tubes (fire inside the tubes) with the steam or water outside the tube.<br /> <br /> <br /> <br /> <script src="http://pub.mybloglog.com/comm3.php?mblID=2010080918203104&amp;r=widget&amp;is=normal&amp;o=l&amp;ro=4&amp;cs=black&amp;ww=220&amp;wc=multiple"> </script><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7529014012524173500-3375265773939916409?l=vjohns1-boiler-gas-controls.blogspot.com' alt='' /></div><img src="http://feeds.feedburner.com/~r/Vjohns1BoilerGasControls/~4/AsiPebU_ijY" height="1" width="1"/>waterfallsnoreply@blogger.com2http://vjohns1-boiler-gas-controls.blogspot.com/2010/08/basic-facts-about-boilers.htmltag:blogger.com,1999:blog-7529014012524173500.post-39966758377262181092010-08-05T01:13:00.000-07:002010-08-05T01:13:38.148-07:002010-08-05T01:13:38.148-07:00 <p><a href="http://feedads.g.doubleclick.net/~a/weTaGUAqBKmpDmB3ioEvtFctz1A/0/da"><img src="http://feedads.g.doubleclick.net/~a/weTaGUAqBKmpDmB3ioEvtFctz1A/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/weTaGUAqBKmpDmB3ioEvtFctz1A/1/da"><img src="http://feedads.g.doubleclick.net/~a/weTaGUAqBKmpDmB3ioEvtFctz1A/1/di" border="0" ismap="true"></img></a></p><div style="text-align: center;"><span style="background-color: #9fc5e8;">What are the main steps when a Boiler fires ?</span></div><div style="text-align: center;"><br /> <a href="http://1.bp.blogspot.com/_Jsr8AZH4jOc/TFpyEq8eBHI/AAAAAAAAAAM/Zs35oF5OQMI/s1600/boiler.jpg" imageanchor="1" style="clear: right; cssfloat: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" bx="true" src="http://1.bp.blogspot.com/_Jsr8AZH4jOc/TFpyEq8eBHI/AAAAAAAAAAM/Zs35oF5OQMI/s320/boiler.jpg" /></a></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">1.Call</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">2.Open Dampers</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">3.Pre Purge</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">4.Pilot</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">5.Main Flame</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">6.End Call</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">7.Post Purge</span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;"><br /> </span></div><div style="text-align: center;"><span style="background-color: #9fc5e8;">8.Off </span></div><div align="left" style="text-align: center;"><br /> </div><div align="left" style="text-align: center;"><br /> </div><div align="left" style="text-align: center;"><br /> </div><div style="text-align: center;"><br /> </div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7529014012524173500-3996675837726218109?l=vjohns1-boiler-gas-controls.blogspot.com' alt='' /></div><img src="http://feeds.feedburner.com/~r/Vjohns1BoilerGasControls/~4/lZNFNvifIGs" height="1" width="1"/>waterfallsnoreply@blogger.com0http://vjohns1-boiler-gas-controls.blogspot.com/2010/08/8-steps-to-firing-boiler.html
