Review on modeling of coal blends for prediction of coke qualityJorge Madias
The operation of blast furnaces with coal/natural gas injection requires high coke quality. For lowest coke cost while keeping the necessary coke quality, the choice of coals and the formulation of the blend is a very important issue. A widely utilized tool for blend design is modeling, preceded by coal characterization and followed by pilot oven testing. In this paper, the development of models is reviewed, based on public literature. Three main stages are taken into account, form the sixties to current times..
Dear Readers,
In this presentation, I have tried to explain main raw material sources of iron making process. Also, with my experience, I have tried to give a concept about the plant engineering related to raw material. I hope that, this presentation will be helpful for young engineers. With this presentation they will get a broad idea about the raw material, based on which they can study more on the subject.
Regards,
Nirjhar.
This topic introduces the methods of irons, steels and cast irons production. It also describes the structure, properties and the usage of irons, steels and cast irons in the engineering field.
Today there are two major commercial processes for making steel, namely basic oxygen steelmaking, which has liquid pig-iron from the blast furnace and scrap steel as the main feed materials, and electric arc furnace (EAF) steelmaking, which uses scrap steel or direct reduced iron (DRI) as the main feed materials.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

coke and metallurgical coal
1. Coke
Introduction
Coke is a hard gray fuel, it bears the same relation to coal as charcoal to wood. Coke is made in
brick furnaces with bituminous coal as the source. Coke is the most vital raw material fed in a blast
furnace operation and hot metal quality. A high quality coke should be able to support a smooth
origin of the blast furnace burden with as little degradation as possible while providing the lowest
amount of impurities, highest thermal energy, highest metal reduction, and optimum absorptivity
for the flow of gaseous and molten products.
Metallurgical Coke
Coke is a solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur
bituminous coal. The volatile constituents of the coal including water, coal-gas and coal-tar are
driven off by baking in an airless oven at temperatures as high 1000° C. Metallurgical coke is
produced by carbonization of coal at high temperatures to produce a macro-porous carbon material
of high strength and relatively large lump size. Metallurgical cokes must have a high strength to
support heavy loads in the blast furnace without disintegration.
Metallurgical Coal
Metallurgical coal is a special type of coal used to make metallurgical coke. There are two types
of metallurgical coal used to make coke;
Hard Coking Coal
Semisoft Coking Coal
These types of coal are ideal for coke because they melt, swell and re-solidify when placed into a
superheated furnace. These types of coal also have low levels of impurities. A third type of
metallurgical coal, PCI (Pulverized Coal Injection) is sometimes used in steel or iron making to
replace more-expensive coke.
The coking coal must have the following;
Low ash content
Low Sulphur content
Porosity factor
Abrasive strength and hardness
Coke Manufacturing
Coke is created by heating metallurgical coal to around 2,000 degrees Fahrenheit. The coking
process takes about 12 to 36 hours in the oven to complete. After being taken out of the oven, the
coke is cooled with water or air to before it is either placed into storage or is put directly to the
blast furnace. The finished product is about two-thirds the weight of the original raw material.
Metallurgical Coke Manufacturing
Metallurgical coke is made from low ash, low sulfur bituminous coal, with special coking
properties, which is inserted into ovens and heated to 1000F to fuse fixed carbon and inherent ash
and drive off most of the volatile matter. The final product is a nearly pure carbon source with
sizes ranging from basketballs (foundry coke) to a fine powder (coke breeze).
2. Factors Affecting Quality
High quality coke is normally made from high quality coking coals. An excellence coal should not
generate high pressure on the coke oven wall and should shrink enough to allow easy removal
from the coking oven. The properties of coke and its performance in the process are influenced by
moisture content, density, weathering of coal, and several other factors.
Application of Metallurgical Coke
Coke is mainly used to make iron, which in turn used as the main ingredient in steel. In
iron making procedure iron ore, coke and small quantities of minerals used to collect
impurities are placed into a blast furnace. Superheated air is then blown into the furnace,
making the coke burn. The burning produces carbon monoxide which reacts with the iron
ore and heat to melt the iron. A tap at the bottom of the furnace allows molten iron, as well
as impurities, to flow out of the furnace.
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The
carbon monoxide produced by its combustion reduces iron oxide (hematite) in the
production of the iron product.
Blast Furnace Construction and Working
Blast furnace consists of a vertical steel shell, 100 ft. high & 21 ft. diameter and lined with
refractory material. It has a charging arrangement (Bell & Cone) at the top. Raw material is charged
by a skip car through this charging mechanism into the blast furnace. It has a means of running off
Pig iron & Slag at the bottom. Air is blown in near the bottom of the furnace. This forced draught
increases the speed of combustion & maintains the necessary high temperature. Cooling water is
circulated around the Bosh area in order to protect the furnace from high temp.
Figure 2 Sketch of Blast Furnace
3. Chemical Reactions Occurring In Blast Furnace Using Coke
In the blast furnace there are several chemical reactions taking place that eventually result in the
desired product (iron) being extracted;
The coke (carbon) burns with oxygen to produce carbon dioxide. This reaction is exothermic.
The CO2 then reacts with more coke to give carbon monoxide.
C + O2 CO2
CO2 + C 2CO
Carbon Monoxide (CO) acts as a reducing agent and reacts with the iron ore to give molten iron,
which trickles to the bottom of the furnace where it is collected.
Fe2O3 + 3CO 2Fe + 3CO2
The limestone in the furnace decomposes, forming calcium oxide. This is a fluxing agent and
combines with impurities to make slag, which floats on top of the molten iron and can be
removed.
CaO + SiO2 CaSiO3

4. Low Ash Metallurgical (LAM), hard coke is used in blast furnace for production of pig iron & in
the production of cast iron.
Low ash coke and low ash coal are widely used as a primary fuel where a uniform and high
temperature is required. Widely used in the manufacture of Silico Manganese, Pig Iron.
