China made hot water boiler in singapore

The important parts, key parts and high alloy parts of the pressure-bearing equipment should be inspected in the process of practical inspection. Taking boiler as an example, the steam drum, header (steam duct, collector header, main steam pipe) heating surface pipe, casting, etc., should be inspected emphatically. It needs to be judged according to the condition of the boiler and reference to the same type of equipment and the actual number of hours of operation of the equipment during the same period.

How natural circulation boiler form a rigid beam and what role? Knowledge and understanding of the boiler, the following forms of learning will be used, is a question and answer of this form, that is, question and answer form to initiate and conduct, so that we can have a good learning outcomes, and questions have a good understanding and correct understanding, so that, when encountered in practical work can be solved in time, and not know what to do, or create new problems, affect the normal use of the boiler, and the results. 1. boiler, natural circulation it is formed? Boiler circulating, is divided into natural circulation and forced circulation of both. In the natural cycle, which is by natural pressure difference between the heating surface and the downcomer, to achieve. Specifically, it is because the density of the mixture in the riser soda, is less than the water in the downcomer the density. Therefore, we can take advantage of this density difference, to make the working fluid flows, without the need for additional external consumption. So, which forms a natural circulation.

What harm grate steam boiler slagging cause? Steam boiler slagging will not only increase the workload of boiler operation and maintenance and overhaul, seriously endangering the safety and economic operation, but also may force the furnace to reduce load operation even forced shutdown. Slagging itself is a complex physical and chemical processes as well as automatically increasing features, once the boiler slagging occurs, since the thermal resistance of the heat transfer deterioration of the slag layer, the slag layer in the furnace and the die temperature are elevated surface temperatures, coupled with slag layer surface roughness, adhesion of slag particles up easier, slagging process results will be intensified. Following a brief set out the harm caused by steam boiler slagging. 1, after the heating surface slag, thermal resistance will increase, decrease heat transfer, reduced working fluid to absorb heat, the exhaust gas temperature increases, to increase heat losses, boiler efficiency is lowered. To maintain the normal operation of the boiler, while increasing the amount of fuel flow rate must be correspondingly increased, which makes the feed, increased loading draft fan, increased auxiliary power, therefore, the economy of slagging steam boiler significantly reduced. 2, when the heating surface slag, in order to maintain the normal operation of the steam boiler, the air flow must be increased. If the ventilation capacity is limited, together with the flue gas channel tends to slagging partially plugged, the flue gas resistance increases, it is difficult to increase the fan flow, forced to down-load operation. 3, the heating surface slagging furnace exit gas temperature rise, resulting in overheating temperatures, combined with thermal excursions caused by slag, Superheater easily cause damage. In this case in order to maintain the temperature and overheating protection reheater, the need to limit movement of the load. 4, slagging combustor nozzle, the outlet stream to change the structure of the burner, so that the condition of the Aerodynamic damaged, affect the combustion process. Severe slagging spout while being blocked, the steam boiler had to down load operation or forced shutdown. 5, water wall slagging, so that it will be unevenly heated parts, adversely affect the safety and control of the flow of hot water wall deviation natural circulation water circulation, may lead to destruction of the waterwall tubes.

The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
