Vertical Type Biomass Fired Steam Boiler
The vertical type biomass fired steam boiler is a small capacity boiler with horizontal water tubes, it fits for the small industries, and has the advantages of compact structure, small footprint, and save infrastructure cost. Flue gas is brushing the inner wall of furnace and water tubes, for radiation heat transfer and convection heat transfer, the grate and lower part of furnace is radiation heating area, the horizontal water tubes and upper part of furnace is convection heating area.
The fuel used for the boiler could also be wood chips, rice hull, bagasse, straw, peanut shell, mustard stalk, cotton stalk, coconut shell, and waste cloth, etc. biomass particle diameter should be 6-10 mm, length should be 25-50mm, and water content should be less than 15%. The source of solid biomass fired boiler fuel is widespread, has the advantages of low cost, environmental friendly (sulfur content<0.06%, and zero CO2 emission), energy saving, and high combustion efficiency (>90%).
Rated Capacity:
0.35t/h~1t/h
Pressure:
<1.6Mpa
Certificate:
ISO 9001, CE, BV, SGS, ASME
Fuel:
Rice husk, wood chips, bagasse, straw, and other biomass fuels.
Boilers Structure
1. The combustion equipment is moving grate or fixed grate, coal or biomass fuel was fed by workers manually.
2. Horizontal pipes increase the radiation heating area, the flue gas pass throught the forced covncection tube bundle longitudinally, fully absorb the flue gas thermal, decrease exhust gas temperature, has high thermal efficiency.
3. The boiler is smoke gas multi-pass structure, has high heat transfer efficiency.
4. The dust in flue gas could remove naturally and ventilate naturally without ID fan and draft fan, could operate quiet.
Auxiliary equipment
INSULATING LAYER
The boiler use aluminium silicate board for heat preservation, has high thermal shielding efficiency and low heat loss.
CONTROL SYSTEM
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
ECONOMIZER
We adopt aluminum alloy fin tubes, its heating transfer area is 2-10 times larger than the bare tube, has a good heating transfer and mechanical property.
WATER PUMP
We adopts the stainless vertical pump with low noise, stainless impeller and pump body.
Steam header
Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.
Water softener
It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.
Quality
Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.
