Low velocity fluidized bed boiler: also called inner circulating fluidized bed boiler, with double drum technology of circulating fluidized bed (SHX) boiler, is the fourth generation of inner circulating fluidized bed boiler developed by ZG, the membrane water wall put the combustion chamber, separator and the fly ash recycle system skillfully arranged into a whole, has the advantages of compact structure and the unique design of the separator structure,a significant advantage is that it can burn coal in poor quality.
The construction of boiler requires that the installation of boiler has certain requirements to the construction of boiler room, and it must accord with the relevant requirements of the state in the process of construction. 1) the boiler house must conform to the regulations of Technical Supervision and Management of Energy Saving of Boiler and Design Code of Industrial Boiler House. 2) the boiler room should be adequately lit and well ventilated, and there should be necessary anti-freezing measures. And boiler rooms should be away from schools, housing and densely populated places. 3) the position of boiler room should be as close as possible to the heating equipment, so as to reduce the head loss of hot oil circulation pump and heat loss of pipeline. 2, Heat-load furnace equipment layout requirements 1 ) the oil storage tank shall be 1 metre lower than the lowest position of the heatload furnace and the heating system in order to clean up the organic heat carriers in the boiler and system, and the oil storage tank shall be spaced not less than 5 metres from the heat carrier furnace or separated by a partition wall. An exhaust pipe shall be installed on the oil storage tank and the diameter of the exhaust pipe shall be one specification larger than that of the expansion pipe. 2) the position of the expansion tank shall be higher than that of other equipment and pipes in the system, and the bottom of the expansion tank shall be 1.5 metres above the maximum liquid level of the system. Do not install directly above any boiler to prevent an organic heat carrier from spilling over to cause a fire. 3) the oil storage tank and the discharge pipe on the expansion tank shall be connected to an outdoor safe place. Valve not to be installed on discharge pipe to protect The storage tank, expansion tank and atmosphere are connected to ensure normal pressure operation. 4) the volume of the high expansion tank should be 1.3 times greater than that of all organic heat carriers in the heat carrier furnace and the whole heating pipe network system under the working temperature due to the thermal expansion. 5) the volume of low-level storage tank should not be less than 1.2 times of the total amount of organic heat carrier in heat carrier furnace. 6) keep at least 0.5 meters of space around the hot oil circulating pump to ensure daily inspection, installation and maintenance.
Effective method of medical boiler drum level measurement of effective methods of medical boiler drum level measurement Currently, the pharmaceutical industry is commonly used in boiler steam boiler, steam boiler will inevitably experience some operating drum level measurement, then the medicine steam boiler What an effective way to measure the water level package has it? drum level measurement can be run on the stability of steam boilers, power and work carried out clearly positioned to ensure its operation in a safe state. Basically, the method of effective medical boiler drum water level measurement can be divided into two, one link type, and second differential pressure. The former can be divided into two-color water level gauge and a measuring electrode type; color water level gauge for determining chromatic aberration by the optical principle; measurement electrode type level gauge is determined according to the difference of the electrical conductivity of soda. The latter name suggests is to a simple determination of the water level changes according to the pressure conditions. In short, whether it is China Unicom type or differential pressure measurements are way more effective, but also more common method of measuring drum level, we can choose according to the actual situation, to effectively monitor the state of the water level in the steam drum to ensure the smooth operation of the boiler and security.
For more than two decades, it has been the focus on clean boilers, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.
