A Liquid Fuel Burner System For Heating The Bed In Pressurised Fluidised Bed Gasifier
A liquid fuel burner device for heating the bed in a pressurized fluidized bed gasifier comprising a pipe (01) forming a housing, a flame stabilizer means (02) disposed in the housing (01) to stabilize and retain the flame by creating mixing and recirculation zones, the recirculation zone contributes the stable flame by constantly igniting the incoming air fuel mixture, it also protects the flame at high pressures from quenching of flame by the abundant process air with high pressure, an oil gun means (04) connected to the flame stabilizer means (02) for atomizing the fuel oil toensure complete combustion of fuel oil and a high energy arc igniter means (07) parallely disposed at an opposite end of the housing (01) to ignite the fuel oil characterized in that the said liquid Fuel burner is capable of firing the liquid fuel continuously in a controlled manner to heat the bed by passing the product of combustion through the bed material, till the bed reached the coal ignition temperature and thereby reducing the process time.
