heat accumulator

1、 The purpose of the heat storage device:
A heat storage device, also known as a steam heat storage device, is a steam container that uses water as the heat storage medium. It is an efficient energy-saving and emission reducing device that improves the reliability and economy of steam use. Steam heat storage devices have a wide range of applications, including steel, metallurgy, textile printing and dyeing, chemical fiber, pulp and paper, brewing, pharmaceuticals, food processing, power generation, and other industries.
The steam accumulator is suitable for the following situations:
1. Heating systems with significant fluctuations in steam load;
2. Heating systems with significant fluctuations in instantaneous steam consumption;
3. Heating systems with intermittent steam generation or large flow fluctuations;
4. Steam needs to be stored for heating systems that can be needed at any time;
5. The heating system for equipment insulation uses steam.
2、 The structural form of the heat storage device:
The form of steam accumulator is generally horizontal and used in conjunction with boilers. The outer body of the heat storage device is equipped with an insulation layer, and the cylinder body is equipped with a steam distribution system, branch pipes, and steam nozzles. The periphery of the nozzle is equipped with a circulation cylinder. Externally equipped with pressure gauges, water level gauges, and automatic control valves. The cylinder is equipped with steam inlet and outlet, inlet pipe and bottom drainage outlet, manhole, etc.
3、 Equipment characteristics of heat storage:
90% of the steam accumulator cylinder is saturated water, with a steam space above the water. When the boiler evaporation exceeds the steam consumption, the excess steam enters the heat storage device to heat the stored water (saturated water), and the steam itself condenses in it, causing the pressure in the heat storage device to rise accordingly. When the steam consumption exceeds the evaporation capacity of the boiler, the stored water (saturated water) in the heat storage device boils due to pressure reduction, providing steam to maintain the boiler load unchanged. The entire work process is controlled by a set of automatic regulating valves. The greater the pressure difference between the boiler pressure and the steam pressure, the more heat can be stored in the heat storage device, and its capacity can be selected according to different situations. Steam heat storage devices are particularly suitable for industrial boiler systems.
4、 Ordering instructions for heat storage devices:
The selection of models and quantities can be based on the installed capacity, rated working pressure, instantaneous maximum steam consumption, steam pressure, and other balance conditions of the steam boiler; Or determine the selection based on the 24-hour steam supply load curve chart and heat balance calculation parameters.
