Hot water boilers include electric hot water boilers, oil-fired hot water boilers, gas-fired hot water boilers, and coal-fired hot water boilers. Hot water boilers are boilers that produce hot water and refer to the heat released by the combustion of fuel or other heat energy (such as electrical energy). , Solar energy, etc.) A thermal energy device that heats water to a rated temperature. “Boiler” as defined in the “Special Equipment Safety Supervision Regulations” refers to equipment that uses various fuels, electricity, or other energy sources to heat the contained liquid to a certain parameter and output heat energy to the outside. Its scope is specified as a pressure-bearing steam boiler with a volume of 30L or more; a pressure-bearing hot water boiler with an outlet water pressure of 0.1MPa (gauge pressure) and a rated power of 0.1Mw or more; an organic heat carrier boiler. Excerpted from the “Special Equipment Safety Supervision Regulations” of the People’s Republic of China.
Product Usage of hot water boiler
Hot water boilers are mainly used for heating and bathing. The hot water boiler circulates the hot water of the insulated water tank through the hot water circulation pump, and repeatedly heats the hot water in the water tank to achieve the purpose of bathing; the hot water boiler circulates the hot water of the heating pipe through the hot water circulation pump, and passes through the radiator (radiator). Can meet people’s heating requirements; hot water boiler and hot water circulation pump combined with heat exchanger can achieve the dual functions of bathing and heating
Use inspection items of hot water boiler
Including boiler internal inspection and preparation, inspection of furnace and flue, inspection of boiler accessories, inspection of automatic control system, inspection of auxiliary equipment, inspection of combustion equipment, inspection of auxiliary heating surface, hot water boiler must be operated before Do some inspections. These inspections are important to us and can cause very serious consequences due to our neglect. Therefore, we must prevent micro-duration, and we must carefully check the following items before running the hot water boiler.
- Including boiler internal inspection and preparation for use.
- Inspect the furnace and flue. Ash and debris in the furnace and flue should be removed. Regulating doors for air ducts and flue ducts must have complete and tight shutters, flexible opening and closing, and accurate opening and closing instructions.
- Check the boiler accessories to check whether the safety accessories are intact; whether the cock is flexible and easy to use; various instruments and control devices should be complete, good and clean. After inspection, the pressure gauge cock should be in working condition.
- Inspection of automatic control system.
- Inspection of auxiliary equipment.
- Inspection of combustion equipment, check whether the combustion device is intact; the test drive of the mechanical transmission system, coal transportation system, and outgassing system is normal; the compression spring of the speed control box should be properly compressed and well lubricated; the indication of the coal brake ruler is correct. The eagle iron is neat and intact, the turning plate is complete, and the movement is flexible.
- auxiliary heating surface inspection, check the auxiliary equipment (inducer fan, blower, water pump, etc.) the coupling is firmly connected; V-belt is properly tightened; lubricating oil should be good and sufficient; cooling water is unblocked. After the inspection is qualified, install the safety protective cover, conduct test operation separately, and pay attention to the current during idling.
