Gas-fired industrial furnaces are used to heat products to a predefined temperature level. As the temperature of the load as well as the composition of the flue gas are crucial for many applications in industry, the controllers of burners have to ensure a given heat input and air–fuel ratio. As a basis for such controllers, an accurate mathematical model of the media supply of an industrial furnace,...
Startup thermal analysis is one of the important aspects of supercritical pressure light water reactor(SCWR) safety analysis. According to the two proposed sliding pressure startup modes, the variation characteristics of different working medium parameters are analyzed in detail. The results show that, the changing of moderator temperature during power increasing process in two modes is different...
Thermogravimetric (TG-DTG) analysis was used to study the pyrolysis characteristics of biology-molding fuel (corn straw and bean straw) at different heating rates in a stream of N2. We determine the kinetic parameters including reaction order, frequency factor and activation energies of straw that guided design for combustion boiler using biology-molding fuel.
The pyrolytic decomposition study of four species of lignocellulosic biomass (pine, poplar, bass and birch) from the Northeast China was carried out by thermogravimetric analysis (TGA) under the temperature range from 30 to 800??C in the N2 atmosphere at four heating rates (??) of 10,20,40 and 60??C/min. The non-isothermal weight loss process of the above biomass samples was mainly composed of dehydration,...
The treatment of waste tyre is a worldwide interested issue. Some studies show that burning waste tyre seems to be a promising and realistic alternative to attain the conversion of waste tyre into valuable and reusable products. In this paper, the experimental study of combustion characteristics of pulverized coal and waste tyre has been conducted by TG-FTIR. The results obtained show that the great...
By means of burning a fraction of comminuted biology-molding fuel and analyzing related parameter and burning characteristics via thermobalanc, the microcosmic burning mechanism of biology-molding fuel verifies Eigen values of curve, parameters of combustion dynamic, providing theoretical reference for high-efficient burning and reasonable application of biology-molding fuel, which consists of the...
The carbonation of CaO calcined from a chemical pure CaCO3 in oxy-fuel combustion condition was investigated in a thermo gravimetric analyzer. The influence of temperature and CO2 concentrations on the carbonation of CaO were investigated. It was found that temperature is very important for CaO carbonation reaction. At the range of tested temperatures, higher temperature can accelerate the carbonation...
Oxygen-enriched (O2/CO2) combustion in circulating fluidized bed(CFB) is one of the most promising clean coal combustion technology which shows good gaseous pollutants control, especially greenhouse CO2. In the paper, the thermogravimetric experiments of Hennan lean coal-char under O2/CO2 and O2/N2 atmosphere have been carried out, the influence of atmosphere, O2 concentration and heating rate on...
Isothermal pyrolysis of biomass such as rice straw, pelletized corncob and pelletized corn straw are studied with the furnace temperature of 700degC, 800degC, 900degC by macro-thermal gravimetric(macro-TG) apparatus. The results indicated that biomass type, particle size, ash contents are influential in biomass isothermal pyrolysis characteristics, larger particle size made inadequate pyrolysis of...
