Introduction of New Generation Waste Incineration Boiler

Equipment Introduction

Cooperating with Shenzhen Hanyang Investment Group Co.,a new type ofvertical rotary pyrolysis gasification series household waste incineration productwas developed,with rated processing capacity of single equipment is 50t/d,100t/d,125t/d and 150t/d respectively.Generally, according to the daily garbage volume,oneor two garbage boiler can be selected to realize the garbage incineration treatmentfrom county-level city.Flue gas or steam generated after burning the householdwaste can be used to dry the municipal sludge,then the drying and dewatering sludge issent into the waste incineration boilers for incineration,which not only makes the harmlesstreatment on the municipal sludge,but also makes the fully ltilization on the calorificvalue of municipal sludge,so as to realize the harmless,reduction and resource coordinateddisposal of household garbage and municipal sludge.

设备特点

(1)The reduction of garbage can reach more than 80%,the burning reduction of residuecan reach less than 5%
(2)Small air disturbance,low dust content in flue gas,low operation and maintenance cost.
(3)Combustion state of secondary combustion chamber can be controlled accuratelyand smoothly.
(4)Small heat loss of slag discharge,high heat energy utilization efficiency of garbage
(5)Good system sealing,low power consumption,operation and investment cost saved.
(6)Heavy metals and other substances are fixed in solid-phase ash directly for landfll.
(7)The slag is discharged after being soaked in the water sealing tank without dustto realize the clean production.
(8)The boiler steam parameters are diversified according to the different capacity andsteam use.Fully considering the safety and economy,the steam pressure can beselected at 0.7~4.1MPa and temperature between 170～400℃ to meet therequirements of garbage incineration resource treatment to the maximum extent.
(9)Reliable operation--Fully considering the high and low temperature corrosion ofgarbage incineration, the heating surface is arranged to avoid away from thecorrosion temperature range,and different materials are selected in differentcorrosion range to extend the service life of the equipment under the condition offully considering the economy of the equipment.

The waste heat boiler and grate independently developed by the group form into thelarge and medium-sized grate waste incineration boiler:

(1)The 200~300 t/d waste incineration boiler adopts the vertical layout with compactstructure to reduce the steel consumption and occupied area.Waste incinerationboiler above 300 t/d adopts vertical +horizontal layout.
(2)Steam parameters can be selected between 1.25~6.4MPa and temperaturebetween 194～485℃.
(3)Reliable operation--Fully considering the high and low temperature corrosion ofgarbage incineration, the heating surface is arranged to avoid away from thecorrosion temperature range,and different materials are selected in differentcorrosion range to extend the service life of the equipment under the condition offully considering the economy of the equipment.
(4)High-speed combustion---Side face of the grate piece is made the mechanicalprocessing,the arrangement gap between the grate is very narrow.Thecombustion air is evenly blown into the furnace at a speed of greater than 20m/sto realize the high-speed stable combustion.
(5)Independent drive---Adopting the independent drive mode to independentlyadjust the operation speed at the drying section,combustion section,bum-out section according to the needs of garbage combustion,so as to ensurethe complete burn-out of garbage.
(6)Modular design---Taking the150t/d processing capacity as the basic unit,torealize the unit processing capacity of 100~200vd through horzontal adjustment,andrealize the large-scale incineration capacity through the horizontal parallel withmultiple units according to the incineration needs.
