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.

Where is the cheapest product for sale? That's right, it's the cheapest unit to sell. All goods are at the factory price is the cheapest, because there will not be so many processes to charge or there will be merchants in the rebate, the same is true of gas-fired boilers. For many people, gas-fired boilers, which are cheaper and of guaranteed quality, need to be purchased directly from manufacturers. Because it saves a lot of money, it will be cheaper when you buy it, but manufacturers are often in their own cities, so if you want to buy the cheapest gas boiler, the best way to buy it is to buy it online. .
