產(chǎn)品簡(jiǎn)介 Brief introduction
防爆電加熱器(流體式)適用于流動(dòng)介質(zhì)的直接加熱、升溫。低溫流動(dòng)介質(zhì)通過(guò)管道在壓力作下進(jìn)入輸入口，沿著電加熱器內(nèi)部科學(xué)設(shè)計(jì)的路徑，帶走電熱元件散發(fā)出的熱量，在電加熱器出口達(dá)到工藝所需溫度。
The expiosion-proof electric heater (fuid.type)is used in direct heating and warming the fow medium.Low temperature liquid medium fows through lhe pipelino and enters the inlet under the pressure. lt lakes away the hea! from eleetrical heating element along the soientific designed path inside the electric heaier, As a result, the temperelure in the outiet of the heater can reach the process roguired temperature.
加熱功率計(jì)算 Heating performance calculation
P-E.C.p.Q. AT
P：介質(zhì)升溫所需功率(W)
C：介質(zhì)比熱(J/g.℃)
P：介質(zhì)比重(g/cm3)
Q：介質(zhì)體積流率(cm3/s)
AT：介質(zhì)輸出口與輸入口的溫差(℃)
E：安全系數(shù)取1.05-1.3
P=E·G·pQ AT
P: medium requlred heating powerW)
C:medium specific heat(J/g℃)
p: medium specific gravity (g/cm3)
Q: medium volume fiow rate (cm3 '/s)
AT:medium tomperature difference between the oullet andinlel'C)
E: safetyfactoruses 1.05-1.3
表面熱負(fù)荷計(jì)算 Surface heatload caleulation
W=P/S
W：熱負(fù)荷(即功率密度)(W/cm2)
P：每根電熱管的發(fā)熱功率(W)
S：每根電熱管的發(fā)熱面積(cm2)
W=P/S
W: heat load (namely power density) (W/cm2)
P: heating power of each electrical heated tube (W)
S: heating area of each electrical heated tube (cm2)
