During the rice harvesting season in Thailand, large amounts of fresh paddy are sent to rice mills immediately after harvesting due to a lack of proper farm storage space. At certain levels of moisture content, rice grains may generate hazardous gases, which can replace oxygen (O(2)) in the confined spaces of underground rice mill pits. This phenomenon has been observed in a fatal accident in T...

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...

It is found that the chemical composition of exhaust gases emitted by IC reciprocating engines includes not only such harmful toxic substances as NOx, CH, PM and CO but also dioxins. Dioxins are characterized by incredibly destructive impact on human health. In the paper a short profile of dioxins, terms of dioxin formation and measures for their reduction are presented. Some experimental data ...

The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...

The paper presents a Process Integration application for waste heat utilisation from exhaust gas streams with partial condensation. It is based on the hot composite curve construction representing gaseous mixture cooling accounting condensable vapour part's gas–liquid equilibrium. With cold requiring heating, Pinch Point determined. On this basis, exchanger network (HEN) structure utilised inte...

The constantly growing number of vehicles sold and operated has resulted in greater contribution automobiles to global pollution. One way reduce emissions carbon dioxide (CO2) toxic compounds, including the particulates nitrogen oxides (NOx) contained exhaust gases, is use alternative fuels. Within this group fuels, those plant origin, mainly alcohols, are attracting more attention because thei...

Introduction: Itqiy is a unique coarse-grained, metal-rich enstatite meteorite that was recovered from Western Sahara in July 2000 [1,2]. The dominating mineral phase is a low Ca pyroxene that partly resembles EL chondritic enstatite. The other main constituent (about 25 vol%) is kamacite, which shows EH chondritic compositional characteristics. Additionally, a few tiny intergrowths of differen...

Abstract This paper presents a streamlined design procedure for water-based noise suppression systems that are applicable to multiple classes of rocket engines. A newly adapted steady quasi-one-dimensional two-phase model is employed predict the evolution exhaust gases interacting with water droplets. Such embedded into two-step optimization objective finding most efficient combination suppress...
