预热室

The hot air furnace is a kind of energy conservation type furnace, composed of burner, furnace chamber, mixing room, hot air outlet and outside jacket, the diluted air in the jacket has two functions, firstly, having insulation purpose: the air belongs to inert gas, it has good insulation function for furnace body, can reach to purpose to cool/protect inside lining and reduce its thickness of furnace chamber; secondly, having preheating function: the gas in the jacket is contacted with hige temperature furnace wall, and enters the mixing room after heat absorption, then to teach the purpose of preheating and energy conservation.

热风炉由燃烧器、炉膛、混合室、热风出口和外夹套构成，是一种节能型炉型，夹套中的稀释空气有两种作用，其一，保温作用：空气属惰性气体类，对炉体有良好的保温作用，达到冷却保护和减薄炉膛内衬的目的；其二，预热作用：气体在夹套中与高温炉壁相接触，吸热后进入混合室，达到了预热节能的目的。

The steam chest ,vapor separators,preheater and surface condenser are designed and constructed for an internal pressure of 1 bar gauge and full vacuum at 121 ℃ except as follows .the shellside of the first effect chest is designed for an internal pressure of 2 bar gauge and full vacuum at 135℃.the bubeside of the prehearter and surface condenser are designed for an internal pressure of 7 bar gauge and full vacuum at 121℃.the equipment is designed and constructed in accordance with asme.certificates are provided.

蒸发分离室，蒸汽室，预热和冷凝器要设计结构内部能够承压1 bar 和在121 ℃充满真空。一效蒸汽室壳侧要设计成能够承压2 bar 和在135 ℃。预热器的管侧和表面冷凝器设计成7 bar 和在121 ℃。设备的设计和制造要符合ASME。要提供证明。

Because preheat and precool increases the chamber charging pressure before the TDC, which is mechanically counter-productive.

因为预热和效果预冷室收费增加了柜台前，贸发局的压力，这是机械。

Any preheating and precooling increases the chamber charging pressure before TDC, and this is mechanically counter- productive for the piston (gas chamber loading requires less mechanical energy in the absence of preheating and precooling, which makes the regenerator less effective than one may think).

任何预热和预冷室收费增加了贸发局的压力面前，这是机械计数器加载生产的活塞（气室需要一个可能觉得少的机械比能量的情况下预热和预冷，这使得再生效果较差）。

The Harper Vertical Screw Furnace preheats incoming material with heat available from the material exiting the hot reaction chamber, doubling energy savings through the reduced energy consumption for both heating and cooling.

Harper立式螺旋窑炉采用由热反应室中出来的原料释放的热量对即将被输送进来的原料进行预热，同时减少了加热和冷却过程中的能量消耗，从而成倍地节省了能量消耗。

Practice of the high blast temperature in 300 m 3BF of Maanshan Iron and Steel Co.Ltd;2. Measures to high blast temperature operation;3. A series of measures for realizing high blast temperature and long campaign have been taken in the design of ex- ternal combustion type hot air stove provided by Nippon Steel for 4350m~3 blast furnace newly built in Taiyuan Iron and Steel Co.

在新建的太钢4350m~3高炉新日铁外燃式热风炉的设计中，围绕高风温长寿命采取了一系列措施：蓄热室、燃烧室、混风室内墙体与拱顶的拱角相接处，采用迷宫式结构，防止独立砌体间窜风；在开孔部位采用组合砖，以提高这些关键部位的气密性和结构稳定性；蓄热室内采用带凹凸槽的小孔径七孔高效格砖，提高加热面积；采用分离型余热回收装置预热助燃空气和煤气等。

The fire coal falls on the chain fire grates from coal: bucket and hen goes into the furnace tank for burning, and the flame passes through the upper back arch of the combustion chamber and back snloke chamber and then through the second fire pipe Io the

燃料煤自煤斗落在链条炉排面上，进入炉膛燃烧后，火焰经过后拱上部燃烧室和后棚管烟室后进入二回程烟管到前烟箱，再由前烟箱折回第三回程管束后，通过热管空气预热器、多管除尘器，然后由引风机抽引经过烟囱排出。

A casting granulated metal equipment by a short flow was developed, which is comprised of pre-heating chamber, heating furnace, ceramic pipe used to transport the molten metal, the holding furnace, the drip nozzle and the cooling tank etc.

研究了一种短流程工艺铸造金属颗粒设备，包括预热室、加热炉、金属熔液输送陶瓷管、保温炉、定量器滴嘴和冷却箱等。

After a time the flow is reversed,the newly heated brick s being used to preheat the air and gas, while the exhaust reheats the checker chambers which have cooled during the first phase.

间隔一段时问，气流改变方向，利用新加热的格子砖来预热空气和煤气，而废气又把前一阶段已冷却下来的蓄热室再加热。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
