Plasma ignition and stable combustion and plasma no fuel in coal-fired power plant technology

Plasma ignition in entirely different from traditional oil gun ignition. Design of plasma ignition in the fuel before combustion of pulverized, atomized pulverized fuels with high-voltage electric arc lights. Compared with conventional oil gun ignition and its advantages as a fuel-saving, environmental protection and safety. Plasma ignition in directly ignited pulverized coal, can save a lot of coal-fired power plant as a quality fuel for ignition. Calculated according to the amount of fuel used per year, plasma ignition device of the operating cost are often compared to a conventional power plant's fuel-assisted ignition devices cost from 10% to 20%. In addition, the use of plasma ignition technology can solve in coal-fired power plant using fuel ignition process of incomplete combustion resulting from smoke pollution, oil gun ignition and cleaner. Plasma ignition and stable combustion technology with dual-scale combustion technique into boiler for other low-NOx combustion technology of low combustion efficiency of solution of the problem. By applying this technology in boiler can also achieve low nitrogen released and steady combustion.

Plasma fuel technology in coal-fired power plant to make power plants are not fuel related equipment and facilities, such as oil and fuel delivery system. Plasma fuel coal-fired power plants rely on its entire operation in the plasma-assisted ignition system of coal-fired set fire to start and stable combustion, power plants create significant cost-saving advantages. In addition, for new power plants, according to the fuel cost saving calculation, also saves fuel expenditure on infrastructure, such as oil and fuel ignition system. Full plasma ignition system as an alternative to the fuel system of power plants can reduce or eliminate the fuel system-related fire accidents.

Retrofitting the steam turbine flow passage

The technology to improve the efficiency of the steam turbines used in power plant and safety through redesign and transformation of steam turbine flow system, thereby improving the efficiency of vapour channel, enhance the efficiency and safe operation of turbines and generators. We have can be applied to different types of flow passage of steam turbine retrofit technology. One of our research projects, 300 MW turbine through-flow with imported technology development and application, and has been included in the 2008 annual national hi-tech industry development projects and investment plans.

Waste heat recovery
Using advanced heat pump technology and to facilitate effective utilization of waste heat power plant of low temperature economizer. Absorption heat pump absorbs heat from the gases emitted by a generator at the power plant, and transmits this heat to the heating system with water. Will help to reduce energy consumption and use of low temperature economizer flue gas waste heat generated by power plants. In case of not affecting the production capacity, energy saving unit.
