After the party soon receive an invitation, we attach great importance to this work, and the exclusion of professional and technical personnel around the boiler safety, the contents of energy saving measures, water quality management equipment, load matching programs have been carefully prepared. After the training, all enterprises and institutions representatives have said that through this training to learn a lot of knowledge of the safe use of the boiler, benefit, will do the safe operation of the boiler in accordance with the guidance of experts.
Routine inspection of boiler energy saving way to check the boiler energy saving boiler is the most basic test. First, the overall boiler internal and external conduct a basic test. Routine testing basic skills boiler inspection, but the requirements of inspectors is higher, boiler inspectors are testing has a wealth of experience and high analytical skills. Hot water boiler steam energy saving Appearance test: First, to test boiler body, particularly the structure of the respective pressure element is reasonable, the pressure receiving surface and the metal member welded seams if there are defects, such as the presence or absence of corrosion, wear, there since no cracks or groove deformation, bracing and without fracture connecting seam, weld surface defect status. Found cracked test suspicious, but they can not only distinguish visually confirmed, can then use a solution of nitric acid concentration of 10% of the suspicious areas wiped clean, and then carefully observed with a magnifying glass to determine whether a crack . If the above test when the steel sheet has adhered dirt scale, a hammer tip may be used to test scale, rust knock, carefully tested after wiping. Energy saving hot water boiler steam hammer test: test hammer holding of local boiler pressure parts need to be inspected tap the appropriate strength, as well as the eyes and ears with hands, which is a comprehensive visual auditory tactile feel there are three kinds of senses to judge defect-free test. Our inspectors can properly grasp this method can be done to determine the correct level. It also reflects our boiler inspectors have a very solid basic skills. Two hammer test is not the same, are flat and round tip, the handle is made of rigid material, we have a special shape narrow neck, an elastic characteristic of the use of the handle to enhance the feel for easy inspection.
The normal shutdown operation of the kg of steam boiler sample computation is to stop the supply of fuel, stop the supply of air, and then stop the air intake; reduce the pressure, maintain the water level, and then close the water supply valve after cooling; close the main air valve, open the steam trap; close the flue baffle.
Four energy-saving methods of gas-fired kg of steam boiler sample computation: energy-saving is a problem to be considered in industrial production, especially the industrial boiler which improves thermal energy and power support for industrial production, and energy-saving reflects the technical level of boiler industry. With the implementation of national energy-saving and environmental protection policies, the traditional coal-fired industrial boilers are gradually replaced by natural gas steam boilers, and a revolution on energy-saving and environmental protection has taken place in the field of industrial thermal power.
To find W, find the mass of the various steam main items from Table 1 150 mm steel main = 28.2 kg/m 150 mm flanges to PN-40 = 28 kg per pair 150 mm stop valve = 88 kg eachLearn More
Jul 25, 2017 · If you dont have any of that information, you could make a general guess at steam flow by calculating the BTUs applied in the boiler, the steam pressure and a boiler efficiency assumption (80% is a decent place to start) to find the amount of BTUs transferred and the amount of BTUs per pound of steam minus the BTUs you started with (based on steam table values for your feedwater temperature) and then back out a decent guess at the steam flow.Learn More
Oct 22, 2016 · Steam Traps are widely employed in Steam distribution network to discharge the condensate from the steam lines as soon as it is formed. This prevents two phase flow in steam lines enabling us in reducing the pressure drop and increasing the life of the pipelines preventing water hammer.Learn More
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.Learn More
Boilers. DSCL ES conducted boiler efficiency measurements on 17 th to 30 th March 2006. Indirect method ASME PTC 4.1 was used for the calculation and losses were identified by field measurements. 2. Measurements & Observations Measurements: Following areas were covered during the test for measurements: a. Water/ Steam parameters.Learn More
4. STEAM GAUGE SYPHON: The device installed between the steam gauge and the boiler to provide a water seal, so that live steam will not enter the gauge to cause a false reading or damage to the gauge.Learn More
and pressures of 17.5 kg per cm2. 2.2.2 Water tube boilers Water tube boilers are designed to circulate hot combustion gases around the outside of a large number of water filled tubes. The tubes extend between an upper header, called a steam drum, and one or more lower headers or drums. In the older designs, the tubesLearn More
boiler contains a safety valve that, when the pressure becomes too high due to blockage or overheating, releases the excess steam. Project Description Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar.Learn More
Steam Consumption Calculation. The following table is prepared to calculate the steam consumption of various processes and accordingly to help determine the boiler type, boiler operating pressure and boiler capacity. However, if the manufacturer of steam-using equipment has specified the amount of steam pressure and steam consumptionLearn More
Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is 100%; of the fuel burned, 90% reacts to form CO2 and the balance to form CO. The temperature of combustion air, fuel and water entering the boiler is assumed at 25oC.Learn More
Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2Learn More
Feb 21, 2019 · A boiler burns coal with the following analysis by mass : Steam Accumulators and Steam Boiler Response to Load Changes For example, if a boiler that has a water volume of only 77 gallons and maintains the header pressure of 125psig is depressurized to 80 psig (minimum load limit), 3.4 percent of the boiler water will flash to steam.Learn More
Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%.Learn More
Saving of each kg of steam is directly proportional to the saving of some percentage of water, coal and electricity.
