Popular Science: What premix condensing gas boiler, which are suitable for places: Nowadays, natural gas boiler generally begin to prevail in our country, whether it is industrial processes, heating or other production industries, natural gas boiler has a shadow.
Because gas-fired boiler is a kind of container equipment with steam and pressure, it is easy to cause accidents if the safety code is not followed in the course of operation, so, Gas-fired boiler operators must follow the rules and regulations to implement the relevant procedures and make good operation and shift records. The following is a high-stability gas-fired boiler manufacturers to introduce what checks should be done before the start of the furnace.
1. When checking the appearance and gas pressure of the boiler, when preparing to start the gas-fired boiler, the on-duty furnace worker should first do a comprehensive inspection, including the appearance of the boiler, the valves and the connecting parts, and then check the pressure of the gas. Ensure that the pressure value is within the normal range, not too high or too low, and that the gas supply valve cannot be opened until it is checked and confirmed to be normal.
2, check the water supply system gas-fired boiler when burning, there should be water inside, otherwise there will be danger. Therefore, before the stove is opened, the boiler workers should check the water supply system and see if the pump can supply water. If the water supply is not properly switched on, the exhaust valve should be opened and ventilated, knowing that the pump can start the water supply. Then open the valves in the water supply system.
3. Checking the water level if too much or too little water in the gas-fired boiler will have an impact on the safe operation of the boiler, it is very important to check the water level gauge well before the start of the furnace. Because the function of the water level gauge is to let the stoves know how much water there is in the boiler at the moment. Therefore, before starting a gas-fired boiler, it is necessary to see whether the position of the water level gauge is normal or not, and also to see whether the level gauge and color plug of the water level meter are in the open position, so as to avoid the phenomenon of false water level, and then to observe whether there is a shortage of water. If lack of water can manually carry out boiler water filling.
Advantages and disadvantages of water-tube boilers SZS gas water tube boilers, gas production base in 20 t / h or more, currently SZS the most popular type of gas pipes, compares it with the fire-tube boiler, no large-diameter drum in structure, rich Alternatively the elastic bending straight pipe smoke tube, not only save metal, and others to improve the capacity of the steam parameters of the boiler to create the conditions. Water tube boiler advantages: 1, the cylinder placed outside the water tube boiler furnace, vary the volume of the furnace, the combustion and to meet the requirements of increased evaporation. 2, water tube boilers generally do not directly heated drum, in order to accommodate the tube was placed in the furnace water vapor, flue heating surface for heat transfer performance and safety can be significantly improved. 3, the water preheating boiler water, soft drinks and the steam superheater in the economizer heating surface, the water wall tubes and convection superheater completed. 4, water vapor boiler system, combustion system and the secondary system is more complex, but the structure of a single water tube boiler pressure parts is relatively simple. 5, since the water preheating boiler water, soft drinks and superheated steam is done in the tube, the tube fouling difficult to remove, and therefore require a higher quality of the water tube boiler, running, operation and management also requires a higher level. Water tube boilers Disadvantages: 1 structure is complicated, manufacturing costs than the fire-tube high, and clean up the trouble. 2. The impact caused a large scale, strict quality requirements. 3. Because the steam drum water reservoir, the water drum capacity is small, it is easy to cause priming phenomenon, the steam generating high humidity. 4. Water prolonged contact with hot combustion gases, easily damaged. The storage capacity of steam is small, so the pressure fluctuation is large.
Our hospital requirements for environmental protection, health and safety in these areas is very high, for a wide variety of market boiler is also very headache and confusion, there fast boiler solve the above problem, the boiler set clean environment to provide for our hospitals and efficient operation in one, coincides with the philosophy of our hospital. --customer feedbackFree Chat
