automatic pellet boiler for central heating

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired automatic pellet boiler for central heating and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

A cleaning and maintenance measures 1, combustion is first opened the door, the rear housing panel removed, cleaning the rear screwing open the mouth of the automatic pellet boiler for central heating; 2, with a wire brush cleaning gas pipe; 3 Dian with a soft brush to clean the combustion chamber; 4 , to remove residue in the boiler, the cleaning opening is screwed on the screw, closing the burner door seal check is complete; 5, when the boiler is installed in areas of a temperature lower than 0 ℃, the following precautions must be taken: If the boiler room in the outdoor the room temperature drops below 15 deg.] C or 18 ℃, that the boiler operating day; if no room for a long time, emptying the water in the boiler should be. Second, you know cathodic protection of each member constituting the boiler (such as iron, copper, aluminum, etc.) of different materials, in order to prevent electrochemical corrosion, cathodic protection measures must be taken. Third, the bottom of the sewage treatment flue gas condensing boiler blowdown can be prevented, because the flue gas condensing flue gas (natural gas or diesel fuel) and the flue gas temperature is too low in the water, the water generated there, part of the moisture is discharged from the chimney, chimney part absorbing wall, the rest is deposited on the bottom of the chimney, the amount of water produced by the following factors: the temperature of the flue gas (91% efficiency, the flue gas must be at a temperature of 170 ℃) where the total surface area of ​​the insulation, chimney and chimney material chimney .

Drum automatic pellet boiler for central heating load adjustment What does it mean? Since the metal-clad steel furnace steam consumption more than 10% to 15% once-through boiler, a relatively large volume of water, so the higher the heat storage capacity of the boiler drum, and drum vapor space can store a certain amount of steam. When the same amount of fuel, when the load changes, the boiler steam pressure changes slower.

Advantage of Water Tube Boiler

Water tube and fire tube boilers are essentially the opposite in design. In a water tube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. In a fire tube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Fire tube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a “pass”. Boilers designed for three-passes have the stack at the rear, and boilers designed for four-passes have the stack at the front. A boiler with more passes has a higher heat extraction rate and is more efficient then one with less passes.
