Comparing with other renewable power generating system, Zichai gasification systerm's characteristic :
1). Flexibility. Gas engine, alternator and even waste heat recovery boiler may be used considering various power plant capacity requirements. It ensures high power generating efficiency. Different capacities of biomass power generation plant can be designed with various types of gasification system.
2). Clean technology. Biomass, as one kind of renewable energy, may reduce the emission of carbon dioxide, sulfur dioxide causing from fossil fuel. Nitrogen oxides emission is very limited in our biomass gasification power generating system because of low temperature (700°C~1200°C).
3). Economic. Gasification is capacity flexible. Even small size biomass power plant is also profitable. Simple process and less land requirements make biomass gasification power plant more economic comparing with other renewable energy. Generally speaking, biomass gasification power generating is the most economic technology in renewable power generating plant, the cost of which is nearly the same as small-size conventional power plant.
ABOUT CHP
Combined heat and power(CHP) also known as cogeneration, is an efficient,clean,and reliable approach to generate power and thermal energy from a single fuel source. By installing a CHP system designed to meet the thermal and electrical base loads of a facility, CHP can greatly increase the facility's operational efficiency and decrease energy costs. At the same time, CHP reduces the emmission of greenhouse gases,which contribute to global climate change.
The biomass gasification power plant is a biomass system that utilizes the biomass as its energy sources. We have included this section about CHP generally to give yoy a better understanding of this increasing interest and technlogy evolving aound this alternate energy option.
Customer Benefits for Syngas-Biomass Engines |
• Cylinders Structure in Line & Upright & Concise Layout, which means simple, easy and low cost in operation & maintenance. Engine-Overhaul can be handled at user's site. |
• Large cylinder (300mm), long stroke, low speed and big displacement 215L and 242L, which means big reserve power capacity and constant power output. |
• Low engine speed at 500 or 600rpm, which means high reliability for continuous operation, sufficient combustion, low exhaust gas temperature and high heat efficiency. |
• Naturally aspirated (no turbocharger and Intercooler), which means low failure rate and minimum downtime (TAR in syngas always block and damage turbocharger and intercooler). |
• Internal mixing system (for high hydrogen gas over 15%), gas and air intake separately, then mixed in combustion room, which means no risk of backfire and cylinder knocking. |
• Strong treatment and resistance ability against TAR, long term trouble free operation. TAR always raises problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc. |
• Compressed Air Starting System, smooth starting, high success rate and easy for maintenance. |
• Open Cooling System, adopting plate-type heat exchanger, high efficiency and easy for scale-removal. |
• Dismountable intake-valve-box, which means can clean TAR easily and conveniently (no need disassembling of cylinder head). |
• Low-speed engine makes the noise lower. The maximum noise ≤100dB. Through silencer, the noise will be ≤70dB. |
• Low speed means low components wearing, namely lower cost in spare parts replacement and long life span. |
• Long Overhaul Time of 60,000 hours and lifecycle of 20-25 years, which ensure sustainable financial rewards of power plant. |
Applicable Gas Fuels • Biomass from MSW, Woodchips, Sawdust, Straw, Rice husks, Nut-shells, and Chicken manure etc. • Industrial tail gas & refinery gas, such as coal gas, coking gas, semi-coke gas, coke oven gas, oilshell tail gas, carbide tail gas, ferrochromium tail gas, yellow phosphorus tail gas, producer gas and paralysis gas etc. |
Requirements for Syngas-Biomass Quality |
Before entering into engine, the syngas should be treated with dust-removal, tar-removal, desulfurization, dewatering and cooling process, to meet up following requirements: |
• Heat value≥4MJ/Nm3; |
• Gas temperature≤40°C; |
• Gas pressure 2.5~10kpa (3~5kpa is better), pressure change rate≤1kPa/min; |
• Moisture Content ≤40 g/Nm3 (without free water); |
• Impurity content≤30mg/Nm3, Impurities particle size≤5μm; |
• Tar content≤50mg/Nm3, H2S content≤50mg/Nm3, Total Sulfur content ≤100mg/Nm3; |
• Ammonia content≤20mg/Nm3, Chlorine content ≤50mg/Nm3 |
• Hydrogen volume content≤50%, Oxygen volume content≤1%; |
• The capacity of syngas pressure-buffering tank should match well with the generator's gas consumption. |
