Product Introduction

DZL series biomass-fired horizontal three-pass water & fire tube chain grate boilers are packaged boilers. By extending the furnace arch, increasing the height of the furnace, adjusting the width and length of grates, etc., ZOZEN has taken the lead in solving the problems commonly occurred in conventional biomass-fired boilers, such as furnace arch burning down, furnace door burnout, backfire in hopper tempering and tube shell coking. This series of boiler has features of wide fuel adaptability, small occupied area, convenient installation and high thermal efficiency.
