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.
The basic cause of the vapor pressure changes 1, external disturbances: vapor pressure changes due to changes in external load, said external disturbance, referred to as "external disturbance." When the external load increases, the unit increases the amount of steam, and boiler have not yet adjusted to the new conditions, evaporation boiler will be less than the required amount of steam outside, the material balance is broken, the vapor pressure drop. 2, internal disturbances: the boiler itself due to changes in operating conditions caused by steam pressure changes, said internal disturbance, referred to as "internal disturbance." No changes in the operation of the external steam requirements, due to changes in the boiler and combustion conditions change (e.g., amount of unstable combustion of fuel or air volume change) and pot operating conditions (e.g., the case of transfer), so that the evaporation zone steam production the amount of change, the amount of evaporation material balance between the boiler steam requirement and destruction, so that the vapor pressure changes.
The normal shutdown operation of the steam boiler 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.
The electric boiler uses electric power as the energy source and uses resistance heating or electromagnetic induction heating to heat the heat medium water or organic heat carrier () to a certain parameter (temperature, pressure) through the heat exchange part of the boiler. A thermal mechanical equipment that outputs a rated working fluid. The definition of a boiler: a boiler is a sealed device that uses all kinds of fuels, electricity or other sources of energy to heat the liquid contained in it to a certain parameter and to carry a certain pressure. The scope of the boiler shall be a pressurized steam boiler whose volume is greater than or equal to 30L; Outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and rated power greater than or equal to 0.1MW Pressure-bearing dzl hot water boiler, organic heat carrier electric boiler. In other words, whatever fuel is used, the prescribed range is the same, except that the fuel heat source is different.[email protected]
