Product introduction

New type high efficiency and energy-saving environmental protection industrial pulverized coal boiler system is a kind of pulverized coal combustion as the core，By the coal reserves, accept, conveying, ignition, combustion and heat transfer, the boiler flue gas purification, automatic control technology sets consisting of new boiler technology system.The main equipment of the new type of efficient pulverized coal fired industrial boiler system including:Pulverized coal bin, rotary discharge valve, the middle bin, screw feeder, a fan, a two fan, pulverized coal burner, boiler host, economizer, dust collector, a draught fan, desulfurization unit, chimney, blowing dust device and automatic control system etc.

Technical characteristics

• 1.Energy saving and high efficiency coal burnout rate reached more than 98%,The boiler thermal efficiency of more than 88%,Boiler with auxiliary gas ignition,The operation can start, fuel saving;Compared with the traditional coal-fired boiler, saving more than 30%;
• 2.Environmental protection cleaning by high desulfurization and dust bag,Dust ≤ 30mg/Nm3,SO2≤100mg/Nm3、NOx ≤200mg/Nm3，Below the national emission standard,To meet the strict requirements of environmental protection;Concentrated powder, concentrated distribution, centralized collection of ash, sealed operation, truly clean combustion;
• 3.Simple operationequipped withmodern automatic control technology,Boiler, coal, combustion, desulfurization dust, slag and other automation control,The fireman less, good working environment;
• 4.Covering an area of saving the system process simple, compact arrangement of equipment, coal and slag does not fall to the ground, no yard, save land;
• 5.Safety and reliability of pulverized coal in pulverized coal tower before furnace sealed storage, to prevent dust and rain; the high reliability program ignition controller, deflagration furnace ignition and burn complete interlock protection; the electrostatic grounding and CO2 protection device, prevent coal spontaneous combustion of pulverized coal tower; these measures are effective to ensure the storage and combustion of pulverized coal safety;
