brief explain water tube boilers
Fangkuai Group insists on using sophisticated equipment and technology to ensure operation accuracy, increase rigidity and surface finish, reduce wear, ensure excellent performance, and ensure stable and reliable manufacturing quality. It has a domestic Class A brief explain water tube boilers manufacturing license issued by the General Administration of Quality Supervision, Inspection and Quarantine. It has been based on quality for many years and has obtained a number of authoritative quality certifications.
Step brief explain water tube boilers blowdown boiler blowdown step 1, the total boiler periodically open the drain valve; 2, the first valve opening a boiler, and then slowly open the secondary valve; 3, after the boiler blowdown is completed, the secondary valve is closed first, after a closed valve; sewage should slowly, to prevent water impact, such as vibration occurs if the boiler tubes and other issues, should stop sewage, and check the cause, until the fault repair during sewage; 4, boiler blowdown process, such as boiler accident, should immediately stop sewage , but the drum level is too high and soft drinks were vacated, except; 5, boiler blowdown ban two boilers at the same time. Boiler water softening equipment raw water from the inlet into the control valve, the valve body through the valve body from the upper portion, by a top (or resin pipe outside the tank, below) into the tank. Then, down through the resin layer (this is a softening, the purge is a carbon layer or the like, the same below), becomes softened water return pipe by the water distributor, up to the valve body, the valve body from the softening equipment discharge outlet. Raw water softening equipment from the inlet into the control valve, the valve body into the inlet nozzle and the outlet nozzle flows quickly, a negative pressure, so that the salt brine tank inlet valve body from the suction port salt, into the tank top.

In fact, from the point of view of energy conservation laws, the thermal efficiency does not exceed 100%. However, there are two values in the professional sector in the gas burner - high heat value and a low calorific value. Of other European countries, like in the definition of thermal efficiency, without the high heat value of the fuel is regarded as a brief explain water tube boilers heat input, the heat thus produced after condensation of water vapor in the flue gas has not been counted in the thermal efficiency.
