gas boiler for central heating and hot water
Coal-fired steam boiler for central heating and hot water scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.
Around the dealers to reflect, party fast always adhere to independent research and design, have their own unique brand of influence, and has a strong after-sales service support system, and such enterprises, have the confidence and motivation. Fang fast a new starting point, opportunities and challenges coexist, hope and difficulties, the Group will continue the fast side and distributor partners across the country hand in hand to create a quick way for a better tomorrow!
Operating cost comparison of different fuel steam boiler for central heating and hot water below Henan fast boiler with small series to introduce the company's operating cost comparison of different fuel steam boiler. Refers to a steam boiler water heated to a certain temperature parameters, and the production of industrial steam boiler, water is heated into steam in the steam drum, the fire in the furnace emits heat, it is the principle of the steam boiler. Steam boiler belongs to special equipment. Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.2 yuan gas / side) fuel: steam boiler advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.5 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 0.6 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 900 yuan / ton).
Select the gas boiler for central heating and hot water should pay attention to what matters now gas hot water boiler, gas boiler equipment application can be described as becoming more widespread, mainly because it compared to the more economical use of its electric boiler. Of course, it is precisely because of this advantage it is also a high degree of concern for this problem which brand of gas boiler. In fact, the choice depends on the gas boiler in addition to its brand should also be aware of the following considerations. 1, factory inspection qualified as most people in the choice of products used to be the center of attention on the price and quality of the product, and therefore qualified for manufacturers in the study is that many users purchase a professional gas boiler IMPORTANT often ignored , not knowing choose a qualified boiler manufacturers are also excellent quality of the equipment and an important way to ensure genuine, and this may be some of the documents from the manufacturers should have the qualification certificate as a gas boiler, quality management system certification and special equipment manufacturing license boilers and other very good judgment out. 2, technical consulting In fact, there are some shopping tips when the user selects the gas boiler will be related to technical advice and communicate with the business, in order to better understand the characteristics and advantages of boiler equipment, but many users will find it a nuisance due go directly to the selected gas boiler equipment they need, and this often takes a lot of time and effort, so here do not recommend this practice. 3, after-sale inspection rules In addition, I must mention is also on the sale of gas boilers emphasis on the content, because you can learn from effective content boiler after-sales business can offer each other provided in compliance with the relevant service itself interests, but also to ensure that their rights and interests by the level of detail after-sales service of its investigation and the scope of protection. It should also be noted that more than a few items when the summary content is to remind everyone in the choice of technologically advanced gas-fired boiler equipment, and the benefits of doing so can also help you find users as soon as possible supply professional and efficient gas boiler equipment, so the purchase also hope that these matters can also be brought to our attention.
