The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
The average boiler steaming rate is 15000 kg/h, and the plant operates for 8000 h/year. The fuel used is gas on a firm tariff of £0.011/ kWh, and the boiler efficiency is estimated as 80%. Make-up water temperature is 10°C and insulated condensate return lines ensure that condensate will arrive back at the boiler house at 95°C.
Mar 28, 2018 · Boiler design-calculation 3. 1. Exercise 7: Thermal Design of A Simple Boiler In this exercise, calculation procedure for boiler design is presented. This simplification is by no means satisfactory for engineering design of the practical facility, but is a reasonable example to discuss some of the fundamental thermal processes in the furnaces
List of Steam Boiler Calculator | Boiler Calculators
The quantity of steam which the boiler generates, usually measured in kg/h. For selecting a blowdown system, the most important figure is usually the maximum quantity of steam that the boiler can generate at full-load. When the above information is available the required blowdown rate can be …
Mar 17, 2015 · 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.
Mar 17, 2015 · Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate ] [ Feedwater Mass Flow = 65.4 klb/hr = 64.5 klb/hr / ( 1 - 0.014 ) ] Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid).
1. Simultaneously Measure Stack Gas Volumetric Flow and Steam Generating Rate. Measure average stack gas volumetric flow (dscfm) using EPA Reference Method 2 Measure average steam flow (mlbsteam/hr) using boiler monitoring equipment 2. Sample Fuel Create composite sample (composed of three approximately 2-pound individual samples)
2. BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.

Mar 17, 2015 · Step 1: Determine Properties of Steam Produced. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow
The specific conductance of a sample, measured in microsiemens (µS) or micromhos (µmho), is proportional to the concentration of ions in the sample. When boiler water is carried over in steam, the dissolved solids content of the boiler water contaminates the steam, and steam sample …
This calculation translates the steam load (in pounds per hour) to boiler horsepower. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5.
Jul 10, 2017 · Corrosion damage in steam-condensing equipment and systems that collect, return and store condensate for reuse as boiler feedwater is a continuing problem at industrial plants, government installations, institutions, hotel, office and commercial buildings. Power engineers long have recognized that steam condensate is corrosive to iron and steel piping systems, and will attack many non-ferrous

A sample of saturated steam is withdrawn through an isokinetic sample nozzle in the connecting links (off-takes) leading from the steam drum to the primary superheater. The steam sample is condensed and the concentration of sodium in the sample is measured. A sample of boiler water from the steam drum is obtained at the same time, and its sodium
In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
