Wood Fired 4 Ton Steam Boiler Supplier
"Euromonitor" closed series of boiler condensate recovery system, the condensed water directly into the boiler temperature, with three-pass boiler air preheater + + economizer, full use of the flue gas heat recovery and then the temperature condensate from the source use, reducing energy waste and significant cost savings for businesses, the effect is immediate.
In hot water boiler, how to prevent back-chamber tube plate crack?
Tubesheet before back to the combustion chamber the boiler work in three backhaul usage worst site, a long period of high and low temperature thermal stress, likely to cause the tube end thermal fatigue cracking, is where this configuration the boiler is the most prone to problems.
Henan condensing gas boiler run Q & A (a) 1. What is the natural cycle of Henan condensing gas boiler? A: The so-called natural circulation boiler, steam and water that are dependent density difference effect evaporator system only, naturally circulating refrigerant boiler. 2. What is the circulation loop Henan condensing gas boiler? A: Henan condensing gas boiler by the drum, down pipe, header, water wall, soft drinks catheter consisting of a closed loop. Henan circulation loop called condensing gas boiler. 3. The natural circulation evaporation system Henan condensing gas boiler which apparatus composed by? A: mainly by the drum, the downcomer, the waterwall tubes, headers and catheters. 4. Why Wall points to a number of cycle? A: Because the uneven distribution of the width of the furnace in Henan condensing gas boiler and the heat load in the depth direction, resulting in heated water wall tubes each wall unevenness, so that the intermediate portion most waterwall tubes heated, heat pipe weaker edge. If the entire wall of a circulation loop consisting only waterwall, the waterwalls parallel, strongly heated water circulating speed large tubes, heated water circulating pipe weak velocity small, the difference in the cooling of the wall. In order to reduce heat waterwall tubes each parallel unevenness, to improve the safety of each parallel tube of the water cycle, usually water wall of each wall Henan condensing gas boiler is divided into a number of cycle. 5. What are the main role of the drum? A: (1) heating the working fluid is evaporated, overheating of the connection hub three processes. At the same time as a balancer to maintain the desired flow of the mixture of soda water wall in the ram. (2) receiving a certain amount of water and steam, together with a great mass of the drum itself, and therefore a considerable amount of heat storage, a change-condensing gas kotelshchik Henan conditions. A buffer capable of stabilizing effect of vapor pressure. (3) mounted steam separator and steam cleaning device, ensure the quality of saturated steam. (4) means for measuring meter and safety accessories, such as pressure gauges, water level gauge, safety valve.
