一、風(fēng)機(jī)的用途
G4-73與Y4-73型鍋爐通、引風(fēng)機(jī)適用于火力發(fā)電廠中2~670T/h蒸氣鍋爐的通、引風(fēng)機(jī)系統(tǒng)。在無(wú)其他特殊要求時(shí),G4-73亦可用于礦井通風(fēng)及一般通風(fēng)。
通風(fēng)機(jī)輸送的介質(zhì)為空氣,最高溫度不得超過(guò)80℃;引風(fēng)機(jī)輸送的介質(zhì)為煙氣,最高溫度不得超過(guò)250℃。
在引風(fēng)機(jī)前,必須加裝除塵裝置,以盡可能減少進(jìn)入風(fēng)機(jī)中煙氣的含塵量。根據(jù)一般電廠使用情況,除塵效率不得低于85%。
二、G4-73型、Y4-73型鍋爐離心通引風(fēng)機(jī)性能參數(shù)表
性能表中提供的參數(shù)。通風(fēng)機(jī)性能按氣體溫度為20℃,大氣壓力為101325Pa,氣體密度為1.2kg/m3的空氣介質(zhì)計(jì)算;引風(fēng)機(jī)性能按氣體溫度為200℃,大氣壓力為101325Pa,氣體密度為0.745kg/m3的煙氣介質(zhì)計(jì)算。
