With the same fresh steam parameters, High Efficiency Turbines Series was 7.2% more efficient than Normal Impulse Turbines Series with significantly lowered steam consumption and more power generation at 2.6MW per hour. Given that the sales price to power network is 0.4 Yuan, and the average annual operating time is 8000 hours, the annual extra economic benefits is: 2.6MW / h × 8000 hours × 0.4 yuan / kw × 1000 = 8320000 Yuan (8.32 million Yuan). These incremental benefits can almost cover the cost of a new turbine. This is the benefits we can bring to our customers.

 With the same fresh steam parameters, High Efficiency Turbines Series heat consumption is reduced by 353KJ/kw.h compared to Normal Impulse Turbines Series with significantly lowered steam consumption and an extra electricity generation of 0.8MW per hour. Given that the sales price to power network of biomass electricity is 0.75 Yuan, the average annual operating time is 8000 hours, the annual extra economic benefits can be as much as: 0.8MW / h × 8000 hours × 0.75 Yuan / kw × 1000 = 4800000 Yuan (4.8 million Yuan).

High Efficiency Turbines series high-speed model, with such characteristics as compact structure, easy installation, smaller size and less space occupancy, can considerably lower our customers’ installation and civil engineering costs.
