Ⅰ . General Descriptions

This boiler is a dual-drum, horizontal positioned and boiling boiler suitable for burning various kinds of biomass fuel. Due to the special feature of fuel and variable operational conditions, a different structure from normal boiling boiler has been designed to meet special requirements.
The boiler body is the same as that of boiling burning equipment. It is composed of main components including secondary drafting system, coal feed device, ignition oil burner, coffee hull and waste feed system, water pipe system, multi-tube duct collector, economizer, air preheater, steel frame, platform and handrail furnace wall.

Ⅱ . Introduction to Typical Boiler

If 14 T/H low pressure boiler operating in Dongguan Nestle Company Ltd is taken as example, the main data are as follows:
1. Type of Boilerdual-drum, natural circulating water pipeindoor )
2.Rated Capacity14t/h
3.Rated Steam Pressure1.96Mpa20kgf/cm2
4.Rated Steam Temperaturesaturated
5.Design Pressure2.45Mpa25kgf/cm2
6.Feed Water temperature104
7.Overall Dimensionsheightwidthlength= 15500890013800mm
8.Boiler Efficiency81% as per the conditions of 3t/h coffee waste + coal
9.Gas Flow at Boiler Outlet30600m3/h154
10. Design Fuel
(1)Coffee waste Cy53.4%Hy3.7%Oy5.5%
(2)Coal oreCy25.1%Hy3.5%Oy15.2%
Qy 9740KJ/kg(2330kcal/kg)
Grain size1.23mm
11.Coal conveying system2 scraper feeders are equipped at the front wall of boiler; coal is conveyed at the port by drafting fan; coal feeding port is 1500mm higher than the center of air button.
12.Fly ash separation system: When ash-contained flue gas goes through convention bank, the ash at bottom will be separated and enter into ash storage through 2 ash hoppers and airlock underneath. At the back of convention bank, there is a multi-tube dust collector for further ash separation from airlock to ash storage. The efficiency under normal operation will be88%.
13.Igniter and coffee waste loading device: 2 oil guns are evenly positioned at the front wall of furnace. There are 4 coffee waste feeding pipes at the right side of coffee-waste feeding device.
14.Soot blower: at the outlet of furnace, there is a rack soot blower and in front of economizer, a fixed rotary soot blower is equipped at preheater of each section.
