Horizontal Natural Gas Fired Hot Water Boiler
Furnace pulverized coal fired boiler is smaller than you: Today saw a piece of content, said: with the same capacity, oil-fired boiler furnace is smaller than pulverized coal. why? The following reasons: the size of the furnace volume, in the boiler capacity is determined, depending on the size of the volume of heat load. Volumetric heat load size is mainly determined by the type of fuel. After the fuel into the furnace, it will take some time to burn. Typically all the required fuel burn before leaving the furnace, the pulverized coal burnout is obviously longer than oil, i.e. coal flame longer than oil. To ensure long-term safe operation of the boiler, not only to prevent the boiler slag, and flue gas at the furnace exit is low to make the temperature at the start of the deformation ratio of ash flue gas temperature 50 ~ 100 ℃, at the outlet of the furnace and to prevent subsequent convection slagging heating surface. In many coal ash content, coal-fired furnace to control the furnace exit gas temperature typically of 1050 ~ 1100 ℃. The fuel oil furnace because very little ash, furnace slag is not dangerous, do not consider the problem of slagging furnace slag discharge outlet pipe, so the furnace exit gas temperature can be higher. For the above two reasons, the volume of the thermal load is higher than Pulverized fuel boiler. Pulverized volumetric heat load is about 145 ~ 185kw / m3, and the volumetric fuel burner heat load of up to 255 ~ 350kw / m3, so the same volume of the furnace fuel burner furnace capacity is relatively small pulverized coal fired.

It is reported that Haidong Qinghai positive response to the central problem of coal-fired boilers environmental supervision feedback rectification work, to speed up the production of green, zero emissions work processes, and improve air pollution control plan before the end of 2020, out of the central regulation of environmental inspectors feedback 10 tons of steam coal-fired boilers and 35 sets of Haidong since 2013, new registrations per hour.
Haidong county (district) government to fulfill the main responsibility for the area out of small coal-fired boilers, in accordance with their respective administrative areas, to develop the county (district) phase out remediation work plan. A thorough inventory of all the region under pressure coal-fired boiler to install and use cases, and register, identify all cases remediation coal-fired boilers since 2013 new registrations do not meet the requirements, filing one by one. It urged all localities to fully consider the urban built-up area, divided ban on burning areas, local conditions, facilities strategy, apply non-urban area Haidong 20 tons of steam per hour, new coal-fired boilers, and establish normal management mechanism. Meanwhile, arrangements for the rectification of funds, and actively apply for provincial, municipal, county departments of special subsidies, to ensure the implementation of coal to gas coal to electricity, coal-fired boiler, new alternative energy and other projects, and with the central environmental inspectors feedback registration illegal small coal-fired boilers problem rectification work combine to promote the problem has been effectively solved.
Select the gas boiler should pay attention to what matters now gas horizontal fired 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.
Steam boilers What is the function? Too many in the form of steam boilers, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.
