kg of steam boiler sample computation

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.
