The present application may be further configured in a preferred example to: the heating water tank and the adjusting water tank are formed by dividing a boiler barrel into two parts, a horizontal isolation plate is arranged in the boiler barrel, so that the boiler barrel is divided into an upper part and a lower part, the heating water tank is arranged above the isolation plate, and the adjusting water tank is arranged below the isolation plate.

By adopting the technical scheme, the heating water tank and the regulating water tank are both positioned in the boiler barrel, the area required when the boiler is installed is reduced, and the cost required for building the boiler is indirectly reduced.

Three-way valve 73 can make two basic adjustments: firstly, when the maximum heating capacity of the boiler is larger than the heat load, the three-way valve 73 adjusts the bypass water quantity, so that the water supply temperature in the water supply pipe 72 just meets the requirement of a heat user on the water supply temperature; secondly, when the maximum heating capacity of the boiler is smaller than the heat load, the three-way valve 73 adjusts the bypass pipe 74 to increase the bypass water flow, so that the inlet water temperature of the boiler is increased, and the boiler cannot reach the maximum heating capacity due to the lower inlet water temperature, namely: the boiler is always operated under the maximum heat supply capacity, and heat is supplied to heat users to the maximum capacity.

In particular: when the height of the expansion water tank 25 is less than 10 meters relative to the top of the heating water tank, the whole set of boiler equipment becomes the 'normal pressure boiler equipment', so that the initial investment and the operating cost of the whole set of system can be effectively reduced. The expansion tank 25 may not be connected to the atmosphere, and at this time, the boiler system is a "pressure-bearing system", and compared with a normal pressure system, the boiler system has a function of reducing power naturally and quickly and can increase the temperature of the supplied water of the boiler.

In the initial state, firstly, nitrogen is introduced from the drain valve 613, and the air inside the boiler barrel 2 is disposed and replaced from the exhaust valve 26 and the expansion tank 25, so as to prevent the boiler barrel 2 from being corroded by the oxygen inside the boiler barrel 2. After most of the oxygen present inside the boiler drum 2 is replaced, an appropriate amount of furnace water is injected into the system piping or the boiler drum 2 through the 613 drain valve, and when the amount of furnace water is sufficient, the exhaust valve 26 is closed. The furnace water is 'electrolyte aqueous solution' formed by adding a proper amount of special electrolyte into pure water.
