1. Syngas heating value can be enhanced at high pressure and low temperature.

2. The variations of lower heating value, theoretical air fuel ratio and combustion potential of natural gas fuel were investigated according to the variation of natural gas composition in China.

3. The higher heating value decreases as the temperature increases and increases as the concentration increases.

4. As a result of low heating value and unsteady component(), ignition and combustion of Municipal Solid Waste(MSW) are difficult using conventional methods.

5. A heating value feedback adjusting system was developed using the airflow heating method to measure the heating value online with air added to the gas to adjust the heating value.

6. The effects of equivalence ratio and volume fraction of oxygen on gas composition, carbon conversion and low heating value of fuel gas were investigated through a series of experiments.

7. In the refuse incineration process, the stability of incineration is always influenced strongly the heating value of refuse.

8. The burner maintains the necessary temperature in primary combustion chamber when burning waste with low or zero heating value .

9. The results show that increasing coal-slurry concentration makes for enhancing cold gas efficiency and syngas heating value at lower gasification temperature.

10. Variations of the process enable production of high purity hydrogen, methanol, ammonia, methane or low heating value gas.

11. The results show that waste output rose continuously, the characteristics of high food scraps content , low recyclable substances content, highwater content and low heating value were gained.

12. In order to ignite the liquids product successfully, ethanol was used as an auxiliary fuel for the heating value determination of liquid product obtained from corn stalk pyrolysis using calorimeter.

13. The coal gases came from two-stage gasification process and the exhaust gases containing combustible components from chemical and metallurgical industries are all low heating value (LHV) gas streams.

14. In the refuse incineration process, the stability of incineration is always influenced heating value of refuse.

15. The SCWO process, on the other hand, can convert virtually all of the heating value of the sludge to hot water or steam without the need for stack gas scrubbing.

16. For ease of trap selection the tables also give the heating value in MBH of the steam condensed.

17. The effects of equivalence ratio and volume fraction of oxygen on gas composition, carbon conversion and low heating value (LHV) of fuel gas were investigated through a series of experiments.

18. In order to produce the biomass synthesized gas which has the main components of H2 and CO with high heating value and gas yield.

19. The measured solar-to-fuel energy conversion efficiency — defined as the heating value of the fuel produced divided by the solar radiative power input — reached 0.8 per cent.

20. When carbon conversion efficiency increases, the gasification temperature decreases, while the yield of dry gas , the heating value and the gasification efficiency increase.
