oil or gas fired water tube hot water boiler price

Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, steam boiler pressure controller and debugging method acting pressure controller is a pressure signal into an electric signal electromechanical conversion device, its function will be the high pressure or low levels of The electrical switching signal to the external circuit for automatic control or chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the oil / gas, and always keep the pressure stable operation. Currently electrical contacts have been rarely used. Above the boiler pressure controller typically uses steam boiler pressure controller are used two to three pressure controller. Wherein a start and stop control furnace, for controlling a large and small fire conversion, there is used an overpressure protection. Two start and stop the boiler pressure controller is generally used to control the temperature controller, pressure controller is arranged to control the two-position and fire the boiler overpressure protection. Three safety accessories on the boiler must be in accordance with the procedures set two, which is intended primarily for safety. First, you can work to prevent another when one of them fails. Second, the purpose of comparison, in particular water level gauge and a pressure controller, to ensure safety, the operator to observe only one of which is the value indicated, but also controls the display shown two values ​​match. 3 generally require a pressure controller, operation is as follows: the first is a power adjusting; e.g. a small fire is set 0.5MPa, 0.4MPa furnace start, the adjustable screw -difference pressure controller (hysteresis) is 1, range (set value) is set to 5. The second pressure is shutdown, diffe set to minimum, range adjusted to 6 (0.6MPa). The third overpressure alarm is set at about 0.7Mpa. Note: the pressure differential must first be transferred back controller adjustment process, and then transferred range. Gas steam boiler pressure controller debugging, generally follow the principle: high pressure, is used as the overpressure protection; high pressure, as boiler start-stop control; low pressure, as a large and a small fire conversion. Specific pressure range may be adjusted according to the nominal pressure boilers and the requirements of use.

1, Safety Precautions: 1 gas oil or fired water tube hot water boiler price room should comply with fire safety requirements, and equipped with the necessary fire-fighting equipment. Storage of flammable materials, such as oil, wood and the like. Non-smoking room, non-smoking room, non-idle personnel and miscellaneous personnel. 2. The operator should be familiar with the structure and performance of hot water boiler components, specifically the installation location and function of the main components, prohibit untrained personnel into the boiler room operation device. 3. A gas water heater enters the room the operator must carry combustible gas, before closing and power, gas chamber must be checked to ensure that the concentration of the gas chamber is not higher than 0.5%, is prohibited switch off transmission. At the same time, we must take effective measures (open windows and doors) for ventilation. 4. Before starting, the supply voltage must check meet the requirements, no phase ground fault or damage, electrical control equipment and mechanical devices meet standard requirements, trouble-free start. 5. Before you start circulating pump must ensure that the system of heat and hot water valve intact, hoist flexible, good pressure gauges, thermometers and other facilities, piping systems leak, the water supply tank water level to the required standard. Otherwise forbidden to open the device. 6. Before starting, you must check the gas supply system to ensure no leakage, pressure is normal, compliance (> 8KPa). If the air pressure is abnormal, the ban starts.

Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, steam boiler essential. Xinjiang Ake Su Xinnong Dairy Co., Ltd. as a local brand, has a large market users. 2016, Akzo increased demand for dairy production, the original steam boiler company can not meet today's production needs. In the same year, Akzo dairy cooperation with our company, signed a series SZS 6 tons of steam pipe steam boilers, steam support for the dairy industry dairy production Aksu.

Structure and characteristics of Water Tube Boiler (double Longitudinal Tube Boiler)

The structure of the double vertical tube water tube boiler is mainly composed of upper and lower vertical tube, convection tube bundle, water wall tube, header box and down tube and other pressure-receiving components. The length of the lower drum is about half shorter than that of the upper drum. The empty space is provided with a furnace, a curved water pipe is arranged between the two drums, and a water wall tube is arranged around the furnace. The burning equipment adopts a gas/oil burner, and the tail flue has an economizer. The boiler evaporation is generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 MPa (MPa). The high-temperature flue gas enters the rear convection flue from the right exit of the furnace, flows in an S shape along the two smoke-proof walls, flushes the convection tube bundle laterally, and then flows through the economizer from the left side of the furnace wall, and is discharged by the induced draft fan and the chimney.
