The small and medium thermoelectric cogeneration turbines designed with full there-dimensional technology were awarded the national key new product title by the State Economic and Trade Commission.

Extraction Condensing Steam Turbine

The extraction points of the extraction condensing steam turbine are set at the proper positions of the turbine cylinder, a part of the steam are extracted from the appropriate middle in the cylinder and supplied to the heat users. The steam turbine for power generation and heat supply is also known as the cogeneration turbine, there are the single-extraction and double-extraction steam turbine at present, which can meet the user's cogeneration needs in different conditions. The extraction steam turbine can effectively reduce the loss of the cold source, and its energy efficiency is very obvious.

Technical features:

The extraction pressure and the steam extraction flow of the extraction condensing steam turbine can be dynamically adjusted in a certain range, and the self-adjustment of thermoelectric load is good. According to user's demand, the turbine extraction parameters can be customized design designed. Under the premise of guaranteeing the long-term safe and stable operation of the turbine, the product will meet the specific needs of various users to a great extent, and it also has the high economical efficiency.

Applicable range:

the extraction condensing steam turbine is applicable to both electric power needs and the place with larger heat load adjustment range, such as incorporating in power grid, regional industrial extraction and heating for living.

Major parameters:

At present, the power range of the extraction condensing steam turbine is 3MW~155MW, the maximum steam admission flow is about 700t/h, the maximum single-stage extraction flow is 300t/h, the maximum extraction pressure is 6.4MPa, and the lowest extraction pressure is 0.118MPa. There is a relative complex inherent rule between the turbine power, extraction pressure and extraction flow capacity. Our Company can provide the turbine model selection calculation for the user at the earlier stage of the project for free, and reasonably match the relationship between three items to select the best model.

The turbine C25-8.83/0.98 designed by CCJEC and CASC is more compact and has a better performance and efficiency.
