烟囱高度 meaning in English
chimney height
height of chimney
stack height
Examples
- Effective chimney height
有效烟囱高度 - Actual stack height
实际烟囱高度 - The predicted ventilation rate increases with solar radiation and solar chimney height
太阳能烟囱的通风量随着太阳辐射强度的增加和烟囱高度的增加明显加大。 - Air temperature inside solar chimney increases with the increase of solar radiation and solar chimney height
气流的温度随着太阳能烟囱高度的增加和太阳能辐射强度的增大而升高。 - Abstract : the in servie tubular heaters built early in refineries and chemical plans have low thermal load and low heat efficiency , therefore measures for technical reform are offered , including ( 1 ) enlarging the surface area of convection tubes to increase the thermal load of rhe convection section ; ( 2 ) increasign the heat interchanging area of radiant tubes ; ( 3 ) changing the height of the chimney ; ( 4 ) using new burner with forced air supply to increase calorific capacityu ; ( 5 ) adding air preheater between the convection section and chimney to enhence the temperature of the air entering the furnace ; ( 6 ) adopting high temperature radiant coating to improve the effect of radiant heat interchanging
文摘:针对早期建造的炼油厂和化工厂在役管式加热炉热负荷和热效率低的状况，提出了若干技术改造措施包括，增大对流管表面积以增大对流段的热负荷；增加辐射管的换热面积；修正烟囱高度；换用新型燃烧器，变自然通风为强制供风，以增大燃烧器的发热量，减小过剩空气系数，节省燃料2 % 3 % ；在对流段和烟囱之间增设空气预热器以提高空气入炉温度；采用高温辐射涂料增强辐射换热效果，从而增加热源对炉壁的辐射传热量和炉管的传热量等。
