Improve the thermal efficiency of the process wns gas boiler, oil-fired boiler which chemical incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass 15 ton fired steam boiler in iraq, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.

Steam boiler pressure gauge should pay attention to matters 1. The rated steam pressure less than 2.45MPa 15 ton fired steam boiler in iraqs, 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.Free Chat
