Main steam is at 2000 psia, 1000 o F, and has an enthalpy of 1474.1 Btu/lbm. Condenser pressure is 1 psia. The steam extraction (cold reheat) pressure is 600 psia, which equates (isentropically
Our oil/gas fired boilers can be divided into SZS 2 ton solid fuel boiler superheated coal fired steam boiler and WNS 2 ton solid fuel boiler superheated coal fired steam boiler depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above.
Benchmarking the fuel cost of steam generation, in dollars per 1,000 pounds ($/1,000 lb) of steam, is an effective way to assess the efficiency of your steam system. This cost is dependent upon fuel type, unit fuel cost, boiler efficiency, feedwater temperature, and steam pressure.
VIETNAM Conversion Rate : US$1.00=Dong 15600 as of Aug 01, 2008. COST OF STEAM PER TON. KIND OF FUEL
steam production rate is reduced, then maintenance costs should more properly be considered to be variable. The second step is to calculate the cost of steam at lower pressure levels. This is not easy, as the cost depends upon the path that the steam follows from the point of generation to the point of use.
Emission factors and ratings for criteria pollutants from anthracite coal combustion are given in Tables 1.2-1, 1.2-2, and 1.2-3. Tables in this section present emission factors on a weight basis (lb/ton). To convert to an energy basis (lb/MMBtu), divide by a heating value of 24.6 MMBtu/ton.
(5) Complete combustion of 1 short ton (2,000 pounds) of this coal will generate about 5,720 pounds (2.86 short tons) of carbon dioxide. Methodology and Statistical Checks EIA's carbon dioxide emission factors were derived from data in the EIA Coal Analysis File, one of the most comprehensive data sources on U.S. coal quality by coalbed and
Annual coal consumption in the United States was virtually steady for sixty years from 1913 to 1973 (at 500 ± 100 million tons per year), except for short-term increases during the two world wars, and a short-term drop during the worst years of the Great Depression (see Figure 7-2). During the last three decades, coal use has been increasing
As an illustration of coal costs, Figure 8.1 show the cost of a ton of US Central Appalachian coal, a coal suitable for power generation, between 1990 and 2013. In 1990 one ton cost $31.6 and although there were fluctuations, the cost remained relatively stable throughout the succeeding decade.
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Heavy working conditions, more than 170 lbs coal/sq.ft. grate/hr - 5.5 lbs water per lb coal, 11,000 lbs water per ton coal This is based on data from a wide range of "modern" steam locomotives (250-300 psi., 2-8-4 to 2-6-6-6.., wherever I could find adequate, consistent info). The figures look more scientific than they really are.
Note 1: In above steam generation cost comparison, all tests are on actual basis at the time of testing and observation. Actual results may vary from mills to mills (location to location) and kind of raw material available at the time of consumption by the user.

in Figure 2.1. The chemical energy available in fossil fuel (i.e., coal, fuel oil, gas) is converted to heat energy by combustion in a steam generator. The heat thus liberated is absorbed by continuously feeding water in a combination of heat-transfer surfaces, resulting in a continuous generation of steam.

Before the beginning of the 20th century, coal was truly the king of commodities. Coal was the dominant source of energy during the tumultuous Industrial Revolution. People still often associate the Industrial Revolution with images of coal mines. Coal is now used primarily for electricity generation (steam coal) and steel manufacturing (metallurgical coal). Besides its

Acoal grate is used to control the rate at which coal is fed into the furnace, and to control the thickness of the coal bed and speed of the grate. Coal must be uniform in size, as large lumps will not burn out com-
Coal contains more carbon than oil or natural gas fossil fuels, resulting in greater volumes of carbon dioxide emissions per unit of electricity generated. In 2010, coal contributed about 81% of CO 2 emissions from generation and contributed about 45% of the electricity generated in the United States.

There are 2000 lb in a short ton so that makes (12000 * 2000) = 24 MMbtu of energy in a short ton of NYMEX coal. If our plant uses 10.412 MMbtu/Mwh and coal is priced in units of 24 MMbtu then we need to multiply the coal price by (10.412 / 24 ) or 0.4226 to get to an equivalent cost of coal to generate our Mwh of electricity.
