Steam boilers can be divided into electric steam boilers, oil-fired steam boilers and gas-fired steam boilers according to fuel. According to the structure, it can be divided into vertical steam boiler and horizontal steam boiler. Small steam boilers are mostly single and double-loop vertical structures, while large steam boilers are mostly three-loop horizontal structures. 1. safety: ① leakage protection: when the boiler leaks electricity, cut off the power supply in time through the leakage circuit breaker to ensure personal safety. ② Water shortage protection: When the boiler is short of water, cut off the control circuit of the heating pipe in time to prevent the heating pipe from being damaged by dry burning, and the controller will issue a water shortage alarm instruction. ③ Grounding protection: When the boiler shell is charged, the leakage current is led to the earth through the grounding wire to ensure personal safety. Under normal circumstances, the protective grounding wire should be well connected with the earth, and the grounding body generally adopts angle steel and steel pipe buried deep underground, and the grounding resistance should not be greater than 4Ω. ④ Steam overpressure protection: When the steam pressure of the boiler exceeds the set upper limit pressure, the safety valve will start to release steam to reduce the pressure. ⑤ Over-current protection: When the boiler is overloaded (the voltage is too high), the leakage circuit breaker will automatically disconnect. ⑥ Power protection: Advanced electronic circuits provide reliable power-off protection after detecting fault states such as overvoltage, undervoltage and disconnection.

2. Convenience: ① After the power supply is introduced into the electric cabinet, the boiler will enter (or leave) the fully automatic operation state with one key operation. (2) The water in the boiler decreases, and the control system automatically replenishes water from the water tank to the boiler through the water supply pump.

3. Rationality: In order to utilize electric energy reasonably and effectively, the heating power supply is divided into several sections, and the controller automatically turns on (turns off) the heating power supply. After the user determines the heating power according to the actual needs, he only needs to close the corresponding leakage circuit breaker (or press the corresponding switch). The hierarchical circulation switching of heating pipes reduces the impact of boiler operation on power grid.

4. Reliability: ① The back of the boiler body is welded by argon arc welding, and the cover surface is welded by hand, which has undergone strict X-ray flaw detection. (2) Boiler steel shall be made in strict accordance with the manufacturing standards. (3) The fittings used in the boiler are all made of high-quality products at home and abroad, and have been tested by the boiler to ensure the long-term normal operation of the boiler. 1. The burners of gas-fired steam boilers are provided by world-renowned manufacturers, and automatically burn and stop according to the instructions of the controller. Independent program controller has many safety protections, safe and stable performance and low maintenance rate.

2. Advanced steam boiler automatic controller, full Chinese LCD screen and man-machine interface. Users only need to set it easily, and the boiler can start and stop, adjust the load and automatically feed water according to users' requirements. The boiler has complete functions, perfect protection, simple operation, safety and reliability, and self-diagnosis function. Once there is an abnormal phenomenon in the operation of the boiler, the combustion will be automatically interrupted and an audible and visual alarm will be given.

3. The vertical steam boiler in Zhuo Yi adopts the way of burner lowering and double return structure, with full fuel combustion and stable boiler operation; The spoiler is inserted in the flue, which slows down the smoke exhaust speed, increases the heat exchange, improves the thermal efficiency of the boiler and reduces the user's use cost.

4. The horizontal steam boiler is a shell-type full-wet reflux three-return pyrotechnic tube structure, which not only improves the heat absorption strength of the boiler, but also meets the thermal expansion needs of the heat exchange surface, and is scientific, reasonable and durable.

5. This boiler is designed, manufactured and inspected in strict accordance with the requirements of Safety Supervision Regulations for Steam Boilers, JB/T 10094-2002 General Technical Conditions for Industrial Boilers and JB/T 16 19-2002 Manufacturing Technical Conditions for Shell Boilers, so as to

6. The furnace liner of the boiler has a large space, stores a large amount of steam, and has strong load adaptability. The built-in steam-water separation device with reasonable design can meet the requirements of users for using high-quality steam. Manholes, head holes and hand holes are arranged in the furnace body, which is convenient for cleaning the inside of the furnace lining and maintenance.

7. Multi-level interlock protection is provided for boiler safety: pressure switch protection (automatic shutdown and alarm when the pressure is higher than the set pressure), low water level protection (automatic power off and alarm when the water level in the boiler is lower than the alarm level), and safety valve protection (automatic deflation and depressurization when the boiler pressure exceeds the working pressure), so as to ensure that the boiler is foolproof under various working conditions and gets home safely.

8. The organically combined mechatronics has exquisite and novel appearance, compact structure, small occupied space and convenient transportation and installation.

9, using new heat insulation materials and high-quality white color steel plate packaging, light weight, good heat insulation performance, beautiful and generous, not easy to rust.

10, fully automatic/gas-fired steam boilers are widely used in hospitals, schools, textile factories, clothing factories, clothing supermarkets, clothing factories, dry cleaners, restaurants, food factories, beverage factories, bean products factories, meat products factories, slaughterhouses, canneries, wineries, pharmaceutical factories, packaging factories and building materials.
