lignite

Meanwhile, RWE, a German utility, is building a plant which will use the residual heat of its own flue gas to dry lignite before burning it.

The results show that the structure and combustion characteristics of lignite had been changed after the degradation.

The technology for capturing and storing carbon emitted by hard-coal and lignite plants is still not commercially proven.

After More burial and chemical transformation of the aging organic material, the peat becomes lignite, a very soft coal-like material.

The results showed that the oxidation degree and aromatic degree of lignite HA was highest, successively with weathering of coal and peat.

Lignite can be dissolved in dyeing wastewater under basic condition, and it adsorbs dyes and exchanges ions quickly in the wastewater.

Natural Resources: coal, sulfur, copper, natural gas, silver, lead, salt, zinc, magnesite, lignite, crude oil.

Mines in the area supply lignite or "brown coal" for power. The electric company in the town is owned by the state.

In order to improve the efficiency of lignite degradation, we mutagenesis white rot fungi by means of ultraviolet ray in the research.

There are large deposits of lignite and oil shale on the island, and significant offshore finds of oil and natural gas have been discovered.

The invention relates to a method for modifying lignite, belonging to the technical field of coal processing.

Reserve of lignite is large, but it has a low rate of using.

The oxidation degree and aromatic degree of weathering coal FA was highest, followed by lignite FA and peat FA.

non-metallic mine to have asbestos, marble, limestone, granite, potash feldspar ore, quartz quarry, sepiolite mining, lignite and so on.

China has abundant coal resources, with low-level resources of lignite and weathering coal in particular.

Lignite size may may vary in processing, the size can be adjusted according to customer requirements.

China is rich in lignite which is not suitable for long distance transportation for its high moisture and ash level and low calorific value.

The tertiary period is an important coal-accumulating period of Northeast China, Lignite is main coal species.

Introduced the application of plasm ignition technique in 600MW direct blowing pulverizing system lignite-fired burner.

The paper also analyzes the operation economy of reciprocating grate boiler fired lignite.

Typical graft bases are brown coal, brown coal coke, lignite and brown coal derivatives, and also tannins.

We use the best lignite or peat, activity humic acid sodium manufacturing .

In this paper, the authors briefly reviewed the research status, results and some problems remained on the coal-forming plants in lignite.

We independently developed the drum dryer to mention quality oxygen-free lignite.

Minerals are mainly graphite and magnesium, while lignite, iron, oil and natural gas.

The invention provides a high efficient lignite heat discharge dehydration system.

Low-rank coals include turf, lignite and leonardite. China has an abundant resource.

Experiments show that the adsorption capacity of lignite is low.

In the lignite matrix, the porosities are mainly meso- and macroporosities.

The pyrolysis of Hailaer and Huolinhe lignite was studied using thermogravimetric analysis.

And this grinding condition is also feasible to other lignite chars.

The highest variety of organic sulphur forms was detected for lignite briquette.

Economy: rich in mineral resources, mainly iron ore, lignite, bauxite, lead-zinc, asbestos, rock salt, barite and so on.

Lignite is dirtier than black coal.

The free gas in the lignite matrix is more than 50 percent of total gas.

The study on coal-forming plants in lignite in China mainly focuses on identifications and classifications of the lignite.

Lignite can adsorb strongly all kinds of dyes, detergents and some heavy metallic ions in solution.
