Gas quenching in an industrial furnace is considered. The flow and thermal fields in the furnace with two different charges, plates and cylinders, in axial flow are studied numerically. Details of the thermal field characteristics are presented. A variation in heat transfer of maximum 125% is ...
The nominal composition of the M951 superalloy is listed in Table 1. The master alloy was cast into 60 mm × 300 mm × 5 mm rectangular plates using a vacuum induction furnace and then subjected to standard heat treatment under the following conditions: 1100 °...
When the ratio of coke-oven gas:blast furnace gas:basic oxygen furnace gas is 2:2:1, the lowest operating cost of the entire system is 95.511 CNY/t-cs, and thus, 5.2619 million CNY can be saved every year. Therefore, the rational allocation and use of by-product gas can bring ...
Technologies exhibiting great potential in emission reduction and high-cost efficiency such as Blast Furnace Top Gas Recovery Turbine Unit (TRT) need to be promoted. (3) In Tangshan city with the highest level of steel production, the iron and steel production activities contributed to the ...
and the influence mechanism of the ratio of typical solid wastes as blast furnace dust(BFD)and sludge generated by oxygen converter gas recovery(OGS)was explored.Meanwhile,the effect of binder solution concentration on the quality of green pellets was studied.Derived from the contact angle dete...
The methodology is used for an industrial furnace where air leakage of 3路1% of combustion airflow and flue gas leakage of 2路6% of total flue gas flow was estimated. The estimated combustion airflow based on stoichiometric reactions is validatedwith experimental data.Sardeshpande...
The quantity of air leakage is estimated based on gaps inside the furnace wall and the differential pressure. The methodology is used for an industrial furnace where air leakage of 3.1% of combustion air flow and flue gas leakage of 2.6% of total flue gas flow was estimated. The estimated ...
It uses pure oxygen instead of air for combustion and recycles part of the flue gas (mainly CO_2) back to the furnace. CANMET and its partners in industry, other government laboratories and universities have carried out large scale retrofit feasibility studies and experimental research on O_2/...
The temperature was raised at a rate of 10 °C/min by an automated PID controller. The sample was held for 60 min after reaching the selected highest heating temperature (400 °C). The biochar sample was cooled to room temperature before being removed from the furnace chamber. The prepared...
Deep eutectic solvents (DESs), a novel and environmentally-friendly solvent, have high potential for biomass pretreatment due to its advantages of low cost, low toxicity, strong solubility, excellent selectivity and biocompatibility. Two types of DES (binary and ternary) were synthesized and characteri...
