Three pass structure hot water boiler for hotel

Within a internal CFB boiler the circulating bed material flows through the furnace together with the fuel and air. Combustion gases are then separated from the solid material with cyclones and any solids are returned to the lower part of the furnace while the gases pass on through the boiler.

Steam under pressure having a certain saturation temperature, when the pressure change, the saturated water and saturated steam temperature change accordingly; shutdown if the boiler pressure drops too quickly, the saturated water and saturated steam temperature dropped significantly . Due to the high rate of change of pressure saturation temperature at a lower pressure, because the upper wall in contact with the drum the saturated steam, saturated with a lower water contact. Thermal conductivity of water is relatively large, the heat storage drum is quickly transferred to the water in the lower wall, the lower the temperature of the drum, close to the saturation temperature at the new pressure after the pressure drop; and poor heat transfer drum upper wall, maintained high temperature, the wall temperature is higher than the upper drum wall temperature, the faster the vapor pressure drop, the greater the temperature difference between the upper and lower walls drum.

Boiler Fan analytical work principle and common installation and maintenance methods? Boiler Fan works: it relies on mechanical energy input, increase the gas pressure of the gas sent to the mechanical side by side, it is a slave fluid machine. Works in induced draft fan and the compressor turbine is substantially the same, but due to the low gas flow rate, little change in pressure, the gas is generally not necessary to consider the change in specific volume, i.e., the process gas as incompressible fluid. Boiler Fan application to blower widely used in factories, mines, tunnel ventilation, cooling towers, vehicles, ships and buildings, dust emission and cooling; the boiler and industrial furnace ventilation and the air; an air conditioning equipment and household appliances cooling and ventilation equipment; grain drying and should select; tunnel and hovercraft air source and the pneumatic propulsion.

In the last meeting on April 16, the hard efforts of audits and company officials of president Mr. Lu Haigang couplet review group to pay thanked rigorous review and couplets group work style, professional skills to express my sincere admiration. Ms. Jiang Lianju warranty division said it will continue to improve the ASME quality control system to ensure produce sophisticated products comply with ASME standards. According to ASME certification process, after the on-site audit, the company will obtain certification and stamp issued within 20 working days, this will be the development of our company in the history of another "milestone" event.
