Automatic Low Pressure Oil Steam Boiler

Automatic Low Pressure Oil Steam Boiler

Steam boiler pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa automatic low pressure steam boilers, pressure gauge accuracy of not less than 2.5; equal to the rated boiler steam pressure 2.45MPa, the pressure shall not be less than 1.5. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Dial gauge diameter of not less than 100 mm, to ensure that the operator can clearly see the surface pressure indication. 2. On the dial gauge steam boiler should draw a red line to indicate the maximum allowable working pressure. 3. The steam boiler pressure gauge should be installed in place to facilitate the observation and purged, and should prevent high temperature, vibration and icing. 4. The steam boiler pressure gauge should be checked at least once every six months, to be sealed lead-sealed after calibration. 5. The steam boiler gauge connection tube not leak water and steam, otherwise it will reduce the pressure instruction value. 6. A steam boiler pressure gauge measuring range should be compatible with the operating pressure of the device under test, the working pressure is generally 1.53 times, preferably 2 times the working pressure. Steam boiler no pressure gauge, pressure gauge or pressure gauge damage does not meet the requirements. When the steam boiler pressure gauge of the following circumstances, should stop using: 1. The surface of the glass or the dial pins; Lead seal, lead seal is broken or exceeds the calibration period; when no pressure gauge pointer position is limited to the limit staple nail can not be restored, and the rank unlimited gauge pointer movement from zero data is out of range pressure layer. Poor; leak or pointer jitter in the meter; other defects affect the accuracy of the pressure gauge. The use of the accumulator: the accumulator for a hydraulic system of the machine intermittently. It may be a low speed motion or intermittent motion of the actuator, the oil reservoir of the hydraulic pump, when rapid movement of the actuator requires a large flow rate, as an auxiliary energy supply to the system together with the hydraulic pump, enabling the pump and the entire hydraulic system miniaturization, to achieve energy saving. Hydraulic shock absorber valve and the opening and closing of rapid mutation load, the system generates a pressure shock, loved one causes vibration and noise and even damage the machine. The accumulator can relax and absorb the impact pressure of the liquid. Accumulators absorb and reduce the pressure pulsation flow pulsation and various hydraulic pumps, thus reducing noise and vibration system. The function of the gas spring having a damper, the vibration can be used to walk between the car body and the wheel and other mechanical absorption. The accumulator may be balance gravity vertical actuator (hydraulic cylinder) and the potential energy absorbing load drop into hydraulic energy storage, while producing speed resistance. When the rising vertical actuator, the accumulator absorbs energy of the original release, and together with the oil pump to the hydraulic cylinders, so as to achieve balance and energy.

For more than two decades, it has been the focus on clean boilers, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.

Combustion Adjustment of dual-use oil and gas boilers (Skills) boiler firing was successful, the load can be adjusted to normal operation. At this point, we should always observe the furnace combustion, if there is a bad oil and gas atomization, beating the flame, the flame hit the furnace and the exhaust gas temperature is too high or too low and so, it is timely for oil pressure, oil temperature, of steam, wind, air pressure, steam pressure hanging line adjustments to ensure safe and economic operation of the boiler. Size and load size of hydraulic, pneumatic boiler related to the oil pressure adjusted by adjusting the back pressure or fuel burner to achieve the size, by adjusting the air pressure to achieve the degree of opening of the valve. Adjust the amount of oil, air pressure adjustment load, at the same time, air volume control, must be synchronized to ensure a reasonable match of oil and the amount of wind, so as to achieve economic operation of the boiler. 1, the combustion method of determining boiler fuel gas: C02 content is determined from the flue gases and excess air ratio (1) the combustion quality (2) determines the length of the flame from the combustion quality (3) from the flame color and smoke color determination 2 is good or bad combustion, fuel combustion boiler adjustment method: the normal combustion, furnace flame stability was white orange, generally rumble, or if the flame beating abnormal sound, should adjust the fuel and air volume. If the adjusted still no improvement, it should identify the cause flameout, the measures to be taken and re-ignition.

The temperature difference between the wall surface of the vertical automatic low pressure steam boiler steam is generated during the vertical steam boiler generates steam, and pressure in the heating, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the temperature of the lower wall, and wall thickness of the vertical bubble there is a temperature difference between the walls, i.e., the inner wall temperature of the bubble is higher than the temperature of the outer wall, the wall temperature is higher than a temperature lower wall, an outer wall and inner wall temperature is higher than the temperature of the inner wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature of the lower wall , the wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature at the wall, the inner wall temperature is higher than the outer wall temperature. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. In order to prevent excessive thermal stress, it is necessary to slow the vertical steam boiler booster. Vertical steam boiler ignition and boosting process conditions steam parameters, each component level and also changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange closely monitor vertical steam boiler various instruments directive professionals change. Since the vertical steam boiler water temperature continues to rise, the metal wall temperature of the bubble and the evaporator heating surface begins to rise at any time, it is necessary to pay attention to temperature and thermal stress of thermal expansion of the bubble, since the bubble wall thickness is relatively thick, so vertical the main problem in the steam boiler heating thermal stress. At the same time, also considering the overall thermal expansion problems, especially vertical tube steam boiler heating surface, since the wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused.
