According to the state of the boiler before and the treatment after the boiler stop, the boiler stop can be divided into the following types:

1.Normal shutdown

When the steam generator stops the furnace normally, first of all, the operating load should be reduced, and then press the stop switch, and then the steam generator automatically stops the boiler according to the program; Start the water pump, add water to the high water level, wait for the steam pressure to drop to 0.3Mpa, and then flush the water table and drain; Finally close the main steam valve; Close the gas supply valve; Cut off the power to the control cabinet.

2.Emergency shutdown

Emergency furnace shutdown is required under any of the following circumstances:

1) When the screen shows “overpressure” and alarms, do not refill the boiler, and immediately stop the furnace and contact the manufacturer to solve the problem before restarting the operation.

2) When the steam generator is in a state of water shortage or dry firing, do not refill water to the boiler, and immediately stop the furnace and contact the dealer or manufacturer to solve the problem before restarting the operation.

1. First of all, according to customer application. Steam boilers are produced in steam, mainly used in food factories, chemical plants, hospitals, clothing factories, power stations and other industries. The hot water boiler produces hot water. It is generally used in commercial and home fields such as Winter heating, bathing room, hotel accommodation.

2.The customer requires rated steam capacity(ton/h). Rated evaporation is the amount of water heated into steam per hour by the boilers. This is our boilers selection need to consider the main parameters. Customers calculate the amount of steam required per hour according to the use of the occasion, such as mushrooms need to sterilize 0.2ton/h, to calculate the appropriate amount of steam according to it.

3.Select the appropriate fuel according to the customer’s own situation. Such as African customers, gas/oil is more expensive, you can recommend biomass/wood boilers for customers.

4. The customer needs pressure and temperature, such as mushroom sterilization needs about 100℃, can recommend 0.4mpa boiler to the customer, the customer can adjust the temperature according to demand.

As we all know, a good hot water supply will directly affect the experience of hotel customers, so the hotel has strict requirements on hot water temperature, heating time and water quality. Hot water boilers heat water to a rated temperature by using the heat energy released by the combustion of fuel. Xinda hot water boiler is equipped with water shortage protection, temperature protection and other protective devices, prevent equipment accidents due to water shortage and high temperature; At the same time with limit low water level protection, in the case of water supply stop will automatically stop working, prevent dry burning caused by electric heating element damage or even burn phenomenon. In addition, hot water boilers also have strict requirements on water quality, we recommend that the boiler before water softener. Users can choose biomass, gas, oil, electric hot water boiler according to the fuel needs.

Sterilization is the most important part of mushroom growth. We should provide a good sterile environment for mushroom growth, otherwise it is easy to affect the growth and yield of mushrooms, serious large-scale diseases. So in the process of cultivating mushrooms, sterilization should be carried out.

Use the Xinda steam generators for 3-5 minutes to produce steam, and adjust the temperature to the appropriate temperature for mushroom growth, which can effectively protect the mushroom strains, kill harmful microorganisms, so as to achieve the effect of sterilization.

Ferment is a very important step in the process of brewing. The most important control temperature for fermentation. The brewing requires constant temperature fermentation, so the temperature control is important. If temperature changes are relatively large, it will have a great impact on the purity and taste of the wine. Constant temperature is difficult to control. But using the Xinda steam generators, it can adjust the temperature when fermentation. Xinda steam generator is automated control, no special person to take care of it. It can produce steam in 5-8 minutes, which is 2-3 times that of traditional brewing fermentation. The thermal efficiency of the steam generator can reach 95%. According to customer reports, the brewing effect of the Xinda steam generators are very good.

Steam generator can be used for food heating, cleaning, sterilization and other aspects. We use more traditional gas steam generators, but this traditional heating way is not stable, and preheat more than ten minutes or longer. On the one hand, it takes time; On the other hand, it’s not too environmental protection.

Xinda small automatic electric steam generators, thermal efficiency up to 95%,3-5 minutes can produce a lot of steam. Suitable for use in catering industry, such as catering disinfection heating. It is the hotel standby equipment.

In modern industry, steam generator can be used for car cleaning and car beauty. Especially in recent years, people began to use steam generator for car washing.

Electric steam generator produces high temperature and high pressure steam by electric heating, and blows away the oil dirt and rust spots of the car under high pressure, so as to achieve a good cleaning effect on the automobile equipment. And it can effectively protect the auto parts, prolong the service life of parts.

Electric steam generator is a small vertical structure, which can automatically adjust the appropriate temperature and pressure. The whole equipment only needs to connect the water source and the power source to generate steam, and the installation is simple and convenient.

Biomass boiler fuel is more widely used, and than other boilers save more than 35% of the operating cost. Biomass fuel is peanut husk, rice husk, straw, weeds, cotton stalks, branches, leaves, wood chips, etc,. but different fuels have certain differences in calorific value.

1. DZH boiler is manual operation fixed grate boiler, its main feature is simple operation, energy saving and environmental protection. DZH series boiler is highest cost-effective boiler,it is praised by our customers many years.

2. DZL boiler is a horizontal single drum three return water and fire tube chain grate boiler,it using a new furnace design,through the built-in three return threaded smoke pipe heat transfer, so that the boiler thermal efficiency up to 82.6%.

3. SZL boiler is a horizontal double drum boiler, it has the advantages of large water volume, large steam space, good steam quality, etc.

Steam boiler operation must maintain normal water level, when the water level exceeds the visible water level, called a full water accident. At this point, if we do not handle it properly, it is likely to affect the quality of steam, and even have serious consequences. Water shortage accident is one of the most common accidents in steam boiler. We should pay enough attention to it and must strictly prevent it. So today we learn about the phenomenon of boiler full of water and treatment measures.

Phenomenon of accident

1, the water level in the water table is higher than the visible edge, invisible water level;

2. High and low water level alarm sends a high water level alarm signal;

3, there is a superheater steam boiler, superheated steam temperature decreased significantly;

4, feed water flow is greater than steam flow;

5, serious steam with a large amount of water, steam pipe issued water strike, flange joint outwards steam dripping

Treatment method

1. Close the gate damper to weaken the combustion.

2. Rinse the water level gauge and check whether the indicator is correct.

3. If the water level indicator is correct, stop the water supply and open the steam boiler blowdown valve for water discharge. Pay attention to the decline of the water level until the normal water level appears.

4. After taking the above measures, if the normal water level still cannot be controlled, the furnace should be stopped immediately.

5. Open the steam trap on the main steam pipe, steam collector and steam master pipe of the steam boiler to prevent water strike in the pipe.
