Hot water heat storage electric boiler Brief Introduction of


(2706.3-504.7) × 0.95 = 3.78 × 103kg of the project in non-heating period,[link widoczny dla zalogowanych], every 13 to provide the steam pressure of 0.2MPa is 3.78T. 3, operational safety and automatic control engineering for the high-temperature water as the heat storage engineering, systems of work pressure is high, to ensure the safe operation of the system,[link widoczny dla zalogowanych], designed with automatic control and alarm measures. In the system, the boiler water temperature, pressure, heat storage tank heat storage backwater temperature,[link widoczny dla zalogowanych], heat storage tank for heating water temperature monitoring, alarm and protection. When the boiler water temperature over temperature when the boiler chain, start over-temperature protection, quickly cut off the heater power. When the system pressure is greater than 0.8MPa, the system opens the pressure relief valve in the discharge. System pressure is greater than 0.85MPa, the safety valve off. Electric Power Survey 'butterfly halo search Gan Xiang 75 {I like the design of electric boiler electric hot water heat storage Brief Introduction of 4 total heat storage system supply pump start and stop according to the following conditions: Measuring the boiler outlet temperature (T), export of heat storage tank Pressure (P), when the measured pressure P is less than the measured temperature T +20 cI = saturation pressure when to start supply pump, pressure P is higher than the measured temperature T +20 cI = saturation pressure +0.2 MPa, the outage compensation pump. Chain store heat pump and electric boilers. Storage heat pump start, the boiler start-up; boiler outage, has heat pump outage. Heat storage system operating personnel daily to check the temperature, pressure and water level, according to a pressure corresponding to the temperature of a water table, determine whether the system need to pay to make up nitrogen, checking system status, to ensure that system operating at design conditions. 4 operating results of the project began operation in November 2000 and has already run two heating season. In the run early, when the construction and installation and has installed anti-pump bypass valve flow, thus creating a system of large water storage heat pump through the bypass back to the population, the flow through the small electric boiler, electric boiler supply and return water temperature difference is large The actual measurements 25cI =. Resulting in less effective boiler room operation. After The transformation of electric boiler return water temperature difference of 12% for the boiler water temperature can reach the end of the regenerative 146cI =. Boiler water temperature through the regulation of electric three-way valves up to 70%. Ensure that the user when the outdoor temperature is lower heating. Boiler room to meet the design requirements of the basic indicators. 5 Conclusion This project is the first case of constant pressure tank with constant pressure, heat storage temperature 145cI ='s hot water heat storage project. After two heating season of operation, the boiler room to meet the design requirements of the basic indicators. In the design and operation of the process, the following points need attention. (1) build a large flow of heat pump hot water pump to be used and has heat flow by 10% of the boiler supply and return water temperature selection. To take full advantage of storing 76; power hoe j2III 'search Gan Xiang butterfly shame jiI respect 4 the thermal storage tank heat for heat pump and circulation pump flow should be 1OcI = temperature selection. (2) Since the heat storage tank heat temperature is 150 ~ C to 70%, for the variable temperature heat for heating safety and energy conservation, the heat pipe design or use of electric three-way valves for the pump frequency, adjust the boiler room heating water temperature. The project uses the electric three-way valve to adjust the boiler room and water temperature, due to a larger adjustment range, the electric three-way valve damaged. Once the electric three-way valve problems can cause over-temperature boiler water temperature. Therefore, the electric three-way valve should be kept for inspection. If the use of frequency adjustment for the heat pump water boiler room temperature, the effect will be even better, you can also save electricity and reduce operating costs. (3) to be installed in the heat storage tank water distributor out of the water pipes, heat storage tank when ordering water distributor providing equipment manufacturers making plans or request them from the heat storage tank equipment manufacturers supporting design. (4) should not be greater than the regenerative system pressure 1.0MPa, temperature is not greater than the regenerative 160cI =. Electric hot water boiler high temperature heat storage,[link widoczny dla zalogowanych], heat storage tanks are smaller, the quality of energy storage high temperature difference can be used. More conventional pressure tank heat storage system,[link widoczny dla zalogowanych], saving boiler room area, providing a high temperature heating water. Apply to schools, residential heating and other general users, also apply to hospitals, hotels and other high temperature requirements of heating the user.
