The methods of this study were to use the heat treatments included hot air, hot water and steam to prevent decay. We measured the temperature in 5 mm depth of the surface on sweet potato in heating treatments and also used COMSOL Multiphysics to simulate the process and to predict surface temperature that was undetectable during heating process to insure the effeteness of heat treatments. After heating treatments, sweet potato were stored in cold rooms at 13~15℃ and 85~100%.

本研究所使用的热处理方法，包括热风处理、热水处理以及蒸汽处理预防贮藏期间的腐烂，并且实际量测甘薯表面深度5 mm处的温度，并使用商业软体COMSOL Multiphysics模拟甘薯在热处理的加热过程中，深度5 mm处的温度与实际加热温度相近，以此模拟推测甘薯表面温度。

Water and steam are typically used as heat transfer medium in heating systems.

在加热系统中，通常以水和蒸汽作为加热介质。

A Place the Jacket Cooling Fresh Water system into the warming up state by operating the cooling fresh water exchange valve of the generator engine or by forcing the steam and the cooling fresh water to flow through the Jacket Cooling Fresh Water heater of the Main Engine.

The mathematical model of complex countercurrent multi-effect evaporation with condensed water flash is established, which aims at minimum annual cost (including cost of fresh vapor, vacuum pump power, evaporator, maintenance and depreciation).Based on such decisive variables as the pressure of fresh vapor, the pressure of condenser and heat-transfer mean temperature difference of vari-effect,the model is solved by the complex method,Lagrangian multiplier method, iteration method and matrix method.The practical example indicates that the influence of the pressure of fresh vapor, the pressure of condenser and flash of condensed water on the optimum design results is notable.

建立了带有冷凝水闪蒸的复杂逆流多效蒸发系统优化设计的数学模型，该模型以整个蒸发系统的年总费用(包括加热蒸汽年费用、真空泵年动力费用以及蒸发器和辅助设备的年折旧维修费用等)最小为优化目标，以生蒸汽压力、冷凝器真空度及各效有效传热温度差为决策变量，提出一种新算法———复合形法结合Lagrangian乘子法、迭代法和矩阵法求解模型。

Close the draw pot and turn back cuff of steam valve , turn on heater steam valve to make liquid material concentrate.

关闭提取罐和夹套蒸汽、开启加热器蒸汽阀门使液料进行浓缩。

Set up appropriate heat regenerative channel of steam to directly flow partial steam until the condenser bottom.

布置适当的蒸汽回热通道，使部分蒸汽直接通到凝汽器底部再加热凝结水，以减小进入热井凝结水的过冷度

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.

拟建项目之废气排放部位为硬质合金件生产线的预热炉（余热加热系统故障采用燃天然气加热时）、熔化炉和精炼炉及机加工机组热处理炉和蒸汽锅炉，污染物为以上部位产生的烟气中含有SO2、NOx以及烟尘，以上各产污设备均采用最清洁的能源——天然气为燃料，同时熔化炉和精炼炉采用低NOx烧嘴等低氮燃烧技术，产生的烟气由烟囱排放。
