latest central heating boiler

Henan how latest central heating boiler plant condensing boilers periodic inspections? Gas condensing boiler is now one kind *** new energy saving device, which works by using the exhaust gas temperature so heat can be fully re-use, greatly improving the thermal efficiency of gas, while the exhaust gas using the process but also some of the hazardous substance removing gas for flue gas emissions are purified. Henan how boiler plant condensing boilers periodic inspections? 1, external examination: in the course of a condensing boiler for use in the external states of the boiler periodically check to ensure that corrosion of the boiler housing no traces of rust, and the connection between the various parts of the loose without loosing phenomenon, the appearance of the boiler deformation does not appear. In addition, welds and heat affected zone of the boiler also check there is no defects such as cracks, where necessary, be checked using the surface inspection or other testing methods. 2, internal inspection: condensing boiler needs a lot of parts for internal inspection, wherein for the previous test of the defective portions, Henan boiler plant using the same test methods to be increased or for the appropriate inspection method has been flawed or defective retesting the repaired area focus retest; head low nitrogen boiler tube plate, furnace combustion chamber and a return header and also must undergo periodic inspection; combustion apparatus in addition also check whether there is a boiler burning, deformation The phenomenon. 3, the hydraulic inspection: the test needs to be tested to a predetermined pressure boiler pressure tightness and strength member is performed when checking for condensing boiler pressure, making the hydraulic inspection time to pay attention not to participate in the communication member of the hydrostatic test (such as outside the scope of boiler pipes, safety valves, etc.) should take credible measures to cut off. If the check is carried out at low temperatures, then we will take effective measures to freezing. Identify selling gas condensing boiler quality should also learn good after-sale technical support case manufacturers, due to equipment failure may occur because of some factors that operation or use of the environment during use, the production of gas condensing boiler businesses must provide regular on-site technical training and detection technology to ensure that the boiler operation.

Oriental Hawaii Holiday Hotel is located in Xiaogan City of Hubei Province in accordance with international five-star hotel standard design, set business rooms, SPA bath, foot care, indoor spa and other facilities in one of the hotel. Hot water latest central heating boiler is one of the important facilities normal operation can not be separated. With the pace of Hubei Province in response to the national defense of the blue sky, the use of clean fuels gradually increase the proportion of Oriental Hawaii hotel provides visitors to the more perfect leisure experience a sense of the original wishing more polluted coal-fired boilers to replace clean and green gas-fired boiler. After comparing several vendors boiler industry, a number of R & D results very fast square value in the field of clean fuels, entered into a collaboration with the fast boiler. Fast boiler integrally provided a 1.4MW condensing pressure hot water boiler (CWNSL1.4-95 / 70-Y.Q) according to their actual needs. Put into use, fully meet the needs of Oriental Hawaii Holiday Hotel heating and hot water supply.

Industrial gas latest central heating boiler room Standard Operating Procedures industrial gas boiler room Standard Operating Procedures industrial gas boiler blast furnace ready to start: gas system: check the gas pressure and the internal combustion engine are matched pressure is normal, not too high or too low, continue under normal circumstances confirm Next. Water supply system: Check the water softening equipment running, the indicators softened water should comply with the relevant national standards. Check level gauge, level indicator switch must be opened, to prevent false water level, to avoid heating the intake air. Check pump for watering, otherwise opening the exhaust valve until the water so far. Stop watering until the water level of 2/3. Close filling pumps and valves. Line pressure: Open inlet and return valve, open No. 1 or No. 2 circulation pump, watching the pressure gauge pressure is normal, the pressure range, and the exhaust air inspection system situation. Electrical system: Check that all control buttons cabinet in an open position, if not open, turn on the switch, turn on the switch to open the order is part of the master switch. Industrial gas boiler flow: System water: Open replenishment pump switch or hand switch is turned on. Another choice is to switch the pump I or II selected pump. (1) is performed before rehydration is necessary to observe whether there is water inside the water softener;. (2) while discharging water and discharged from the bottom up high-rise buildings, water supply until the water flow stable and stops. Start boiler front pump (circulation pump), to open the boiler control cabinet, open the internal switch, the cabinet door closed, the circulation pump start switch is pressed, a green light, running forehearth pump (circulation pump), so that a uniform water circulation system. Start boiler: Press the boiler switch red switch button intelligent digital boiler controller, then press the green Start / Stop button, the green light and burner wind, wait a few seconds, the engine ignition, start a normal combustion. Check the record: all the equipment and check the pipes regularly check the boiler. Industrial gas boiler start-ignition combustion: ensure the main power switch, a button to open the burner, fan sweep should begin immediately. Burner ignition failure, fault lights for 20 seconds, press the reset button to restart consecutive three or four ignition failure, successful ignition, should be reported to repair. When the burner is closed due to some failure, each system should be checked to confirm or displacement. After the fault is acknowledged and eliminated, the burner will restart.

The water vapor partial pressure may know, latest central heating boiler exhaust gas dew point temperature is generally 55 ~ 60 ℃. We reduced by the refrigerant medium (e.g., cold water, cold air, etc.) to a flue gas temperature of flue gas temperature below the dew point, the condensed water vapor in the flue gas can be recovered sensible heat and latent heat of the flue gases at the same time. Calculating the thermal efficiency is low calorie fat conventionally as a reference, is included in the latent heat efficiency of the boiler after steam heat may exceed 100%. And because the water vapor condensation process condensed water may absorb a portion of the harmful gases (e.g., S02, NOx, etc.), reducing the pollutant emissions, environmentally friendly. Per standard cubic meter of combustion gas can be generated in Northern approximately 1.6kg of water, gas boiler fuel consumption of about 0.7MW 80m3 / h, if half of the generated steam is cooled down, may be generated 80 × 1.6 x0.5kg / h = 64kg / h of water, you can see the amount of water available is considerable, if taken measures to make use of this part of the water, the water shortage in some areas will have a positive effect.
