Gas boiler SZS, WNS, F, A, L, N, B and other parameters have what meaning? SZS gas boiler water is commonly used parameters. Wherein the meaning of each letter, S: double drum. There are two drum boiler, goes under the distribution structure. Z: vertical type. Using the "D" type arrangement, arranged longitudinally down drum, as the flue gas flow partition Wall full mode, the left side of the boiler convective tube bank is arranged. S: combustion chamber. Fuel is powdered (solid fuel, such as coal), mist (liquid fuels, such as oil), gaseous (gaseous fuel, such as natural gas) along with the air into the furnace (combustion) combustion in suspension. WNS is automatic gas (oil) parameters commonly used boiler. In which the meaning of each letter, W: horizontal. A boiler according to the design and installation of the outer layout, was lying state. An exhaust gas stream produced by the boiler is of horizontal flow, the flow of hot gas, in the same section on the exhaust gas temperature is low compete. N: internal combustion. After all of the fuel combustion flue gas, without burning the residue was heated with a heating surface directly mixed working fluid (water), and the flue gas, steam as the working fluid work output, the flame in the combustion furnace through the center of the drum. S: combustion chamber. Fuel is powdered (solid fuel, such as coal), mist (liquid fuels, such as oil), gaseous (gaseous fuel, such as natural gas) along with the air into the furnace (combustion) combustion in suspension. F: split. A: three return. N: N is low. L: condensation. B: Center backdraft.
13th of this month, Jiangsu Province, held a working meeting air pollution control, meeting the main objectives and tasks around the year, and plan the next phase of priorities, from morning to promote strict air pollution control this year's tight.
First, in-depth treatment of industrial pollution, dehumidification start off white along the Yangtze River coal-fired power project to promote the electricity, steel, cement, coke, glass, carbon, boilers, furnaces and other key industries the full implementation of the transformation of ultra-low emissions, the province basically completed iron and steel enterprises sintering machine ultra-low emission transformation, cement, coke, glass, carbon industry to achieve the emission limits set provincial requirements.
More details gas boilers should be promptly after use as a burner for steam boiler with good quality plant drainage, heating, bath with gas boiler is a kind of fuel for the gas equipment (fuel gas-fired boilers), because it is compared with oil-fired boiler, electric boiler up more economical, which is widely used. After carrying out the gas boiler must turn on the water to be disabled. Why is that? We will come and detailed discussion about this issue today. To turn on the water when the gas boiler is disabled: gas boiler in the boiler water if the winter will put the cracking, there will be odor and summer long embroidered, so that the life of the boiler will be reduced. At the bottom of the boiler there is a turn on the water with the section of the door, then opened, gas boiler pipes in the water will flow back to the boiler, the boiler is done and the water on it. Water level controller SZB-IV (electrode type water level alarm) 1. When the normal level of + 30mm, pump control switch contacts are open, the pump stops working. 2. When the normal water level -30mm, pump control switch contacts in contact, the pump starts to work. 3. When the normal water level of + 50mm, a first group of electromagnets high gas boiler water level contacts the combined output high level alarm signal. 4. When the normal water level of the gas boiler -50mm, a second group of electromagnets in conjunction with the low water contact output low water level alarm signal.
Electric burner for steam boiler with good quality to be taken by each of the cathodic protection measures components of the electric steam boiler is made of different materials. In order to prevent galvanic corrosion, cathodic protection measures must be taken. Sewage treatment electric steam boilers. Bottom electric steam boiler blowdown can prevent flue gas condensation. Since the flue gas is flue gas condensation (diesel or natural gas) and the flue gas temperature in the aqueous too low, water generated. A portion of the moisture is discharged from the chimney, the chimney wall is absorbed, the rest is deposited on the bottom of the chimney. Water produced by the following factors influence: flue gas temperature (efficiency 91%, the flue gas must be at a temperature of 170 ℃) where the total surface area heat chimney, chimney and chimney material. Maintenance of the burner. Electric steam boiler and burner maintenance, repair after steam supply. Because the products of combustion will corrode the boiler, clean up carbon deposits, therefore, not allow the products of combustion in the boiler memory stay too long. We first opened when an electric steam boiler burner door, the rear housing panel removed, unscrew the screws electric steam boiler cleaning the rear opening. Clean fuel gas piping with a wire brush. With a soft brush to clean the combustion chamber. Electric steam boiler to remove residue in the boiler, the cleaning opening is screwed on the screw, closing the burner door seal check is complete. If electric steam boilers installed in areas where temperatures below 0 ℃ must take the following precautions: If electric steam boiler room outside, the room temperature drops below 15 ℃ or 18 ℃, the electric steam boiler running all day long. If no one in the room for a long time, the water should be emptied in electric steam boilers.
