Characteristics of pressure boilers for pressure hot water boilers

1. The horizontal pressure hot water boiler is a horizontal internal combustion wet-back boiler. Its main structure is composed of a pot shell, a furnace sleeve, a smoke chamber, a smoke pipe, etc. Imported burner is selected, suitable for a variety of gas and liquid fuels.

2. The main body of the boiler is produced in strict accordance with JB T7985 95 "General Technical Conditions for Pressure Boilers" and extremely relevant standards.

3. The flue gas process adopts a three-way arrangement, a wet-back structure with full butt welding, and a large heating area.

4. The inner tank is a corrugated bile (or straight furnace bile bladder), the smoke box is an asymmetrical eccentric structure, and the convection section is inserted with a spoiler to optimize the smoke range.

5. Equipped with high-quality imported burner (low NOx burner), the harmful components in the flue gas are lower than the national standard (NOx emission is less than 400mg m3), which is an environmentally friendly product. Pressure atomization, complete (oil) combustion, low noise, safety and efficiency, and environmental protection indicators are in line with national requirements.

6. The smoke exhaust port can be equipped with a condensing heat exchanger (optional), and the water vapor in the condensed flue gas absorbs the latent heat of condensation, so as to improve the thermal efficiency of the boiler.

7. The boiler body runs under pressure, and adopts dual signal control of pressure and temperature, which has no hidden dangers.

8. It adopts advanced touch screen controller and digital control system, which has the functions of timing control, work record and leak detection alarm, and can add a manufacturer's timing lock.

9. The boiler operation is fully controlled, the outlet water temperature is automatically adjusted, the boiler automatic ignition program is started, and it is equipped with a variety of alarm interlocking protection devices to ensure the efficient, safe and reliable operation of the boiler.

10. Perfect shape design, bright appearance color, elegant and fashionable, compact structure, beautiful appearance, overall quick installation factory, easy transportation and installation.

Pressure boilers are important equipment used in large industrial sites such as factories and power plants to produce steam or high-temperature water. In order to ensure safe and stable operation, the pressure boiler should meet a series of technical conditions, which include:

1.Working pressure: refers to the maximum allowable working pressure of the pressure boiler, usually expressed in MPa.

2.Operating temperature: refers to the maximum allowable operating temperature of the inner wall of the pressure boiler, usually expressed in degrees Celsius.

3.Flue temperature: refers to the maximum allowable temperature during flue exhaust discharge.

4.Design parameters: Some important parameters should be taken into account when designing pressure boilers, such as heating area, furnace volume, fuel type and grate area. Setting these parameters reasonably will help to improve the efficiency and reliability of the boiler.

5.Safety protection device: The pressure boiler needs to be equipped with a variety of safety protection devices, such as pressure gauges, automatic control devices, safety valves and superheat protectors, etc., to ensure that timely countermeasures are taken in case of abnormal situations.

6.Regular inspection: Pressure boilers need to be regularly inspected and maintained, as well as inspection records in accordance with national and industry standards. Safety technical indicators such as weld and material testing should meet the standards.

The above are some common technical conditions for pressure boilers. During design and operation, it is necessary to follow the appropriate national and industry norms and ensure that it operates safely and reliably.

Hello, (1) The boiler of the pressure hot water boiler heating system is a pressure equipment, which has the greatest danger. The boiler of the atmospheric hot water boiler heating system is not pressurized and always communicates with the atmosphere, so the boiler will not be the best under any circumstances, and the safety performance is good.

2) The pressure hot water boiler is full of water, and there is no water level control problem. Atmospheric hot water boilers have water level control problems. It is a boiler with a full barrel of water, and the top is still connected to an open box, and there is still a problem with water level control.

3) The pressure hot water boiler must be equipped with a pressure gauge, a safety valve and a thermometer, because the boiler is always in a full state, so there is no water level gauge, and the atmospheric hot water boiler only has a water level gauge and a thermometer, because the boiler is connected with the atmosphere, the pressure in the pot is always atmospheric pressure, and there is no danger, so there is no need to install a safety valve, and you can also not install a pressure gauge.

4) The circulating water pump of the heating system of the pressure hot water boiler is the return water of the pumping system project to the boiler, and the clean water pump is generally selected. It not only has to overcome the system circulation resistance, but also to maintain a certain pressure of the boiler to ensure that the boiler water does not vaporize at high temperatures. The circulating water pump of the heating system of the atmospheric hot water boiler is to pump water from the boiler, and the water pump is a hot water pump, whose function is to overcome the resistance of the system, mainly to overcome the resistance of the return water control valve.

5) The pressure hot water boiler can not only supply low-temperature water, but also high-temperature water. The atmospheric hot water boiler can only be less than 100 low temperature water.

Atmospheric hot water boiler: Atmospheric pressure is the general normal atmospheric pressure. Atmospheric hot water boilers can be said to be unable to withstand pressure.

Pressure hot water boiler: During normal operation, the furnace can carry the rated pressure. Pressure boilers are divided into medium pressure, high pressure and ultra-high pressure. It is medium pressure, 10 100 is high pressure, and > 100 is ultra-high pressure.

Atmospheric boiler is a boiler that does not bear pressure, and the boiler is connected with the atmosphere, that is, a non-pressure boiler.

A pressure boiler is one in which the boiler and pipes are under pressure when it is running.

They operate differently: the water pump of the atmospheric boiler sucks the hot water from the boiler to the pipeline, and the boiler is pressureless. The pressurized boiler is to suction the water from the pipe into the boiler and push the hot water of the boiler away, so the boiler is pressurized.

Answer]: A This question assesses the type of rock bridge that divides the boiler according to the pressure. Boilers are divided into pressure, atmospheric pressure (non-pressure) and negative pressure (vacuum) boilers according to pressure. Electric boilers are marked by fuel. Therefore, it is wrong to choose a town fierce item.

1. Pressure boilers are divided into steam boilers and pressure hot water boilers. The atmospheric boiler is to have a normal atmospheric hole, and the maximum pressure of the boiler cannot be exceeded, and the pressure hot water boiler means that the hot water used by the boiler cannot exceed 90 degrees, but it can be installed under pressure during the installation process.

2. There are too many famous boiler manufacturers, the key is what you learn, you can go to the boiler network to see.

The internal pressure of the pressure boiler is higher than the atmospheric pressure during operation.
