Fire Tube Oil and Gas Hot Water Boiler for Hotel Central Heating

Henan gas boiler before which components should be checked before checking Henan gas furnace tube boiler, furnace, pipe tobacco, and other head and bracing member whether the normal pressure, with or without severe corrosion or deformation, cracks, gas boiler Henan left without inner scale, impurities, with or without tools objects, etc., and confirmed no one in the boiler, before they close all manholes, hand holes, into the holes, hand holes, the cover should be put gland n, should rubber ring or asbestos mat asbestos mat prepared cords asbestos rope between the manhole cover. To avoid the use of the mat, is bonded to the edge of the hole or holes of the cover, the two contact surfaces to be coated mat black oil and a mixture of lead powder, white lead oil to stop. Henan gas boilers, boiler external inspection for damage, the furnace heating surface should be checked, whether the heat insulation layer intact. Or whether there is residual fuel in the furnace soot within the examination. Chimney device can be reasonable. Check whether the position extinguishing apparatus reasonable, easy maintenance can extinguisher, heating pipes can open, close, barometer indicating whether correctly, the fan, the motor can properly steering damper can switch sensitivity. Conditioning installation can load the correct position, ignition electrodes, ignition position, the position of a small fire, the fire can preset position is good. The circulating pump leak-free, noise-free and temperature anomalies, adhere to the bearing housing oil level is normal, water outlet pipe flow. Henan gas boiler water treatment equipment, deaerator commissioning, check the boiler feed water feed water can reach the kingdom of the request.

Hebei Cangzhou issued a "special program on the implementation of standards of governance boiler." Emission standards for boiler treatment and corresponding indication made, as shown in details as follows.

First, the standard standard coal-fired boiler

1, before the end of September 2019, within the city of more than 35 tons of steam / hour ultra-low emission coal-fired boilers complete transformation, emissions of major pollutants to achieve ultra-low emission standards (dust ≤10mg / m³, SO2≤35mg / m³, NOx≤50mg / m³).

Before the end of the year 2/2020, the city eliminated 35 tons of steam / hour and coal-fired boiler, stove and stove operating a small coal stove, achieved within the city 35 steam tons / hour and the boiler "No Coal." Reserved 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove implementation of the special emission standards (dust ≤30mg / m3, SO2≤200mg / m3, NOx≤200mg / m3).

Retention of more than 35 tons of steam / h coal-fired boiler to install air pollution automatic monitoring facilities and networking with the environment department, to install a distributed control system (DCS system), real-time monitoring of pollutant emissions.

Second, gas-fired boiler

1, before the end of September 2019, the city completed two-thirds of the total number of units of low-nitrogen transformation gas boiler above. Among them, the central city of all gas-fired boiler and all the city's industrial and commercial gas-fired boilers to complete a full rebuilding mode low nitrogen.

2, the end of June 2020, the conventional gas boiler should be completed by transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxide respectively 5mg / m³, 10mg / m³, 30mg / m³.

Third, the task

1, increase clean energy alternatives. In areas not covered by central heating pipe network, and vigorously promote geothermal, wind, solar and other clean energy, in an orderly way from coal to gas and coal to electricity, to change the power-based. In 2020, under the conditions of gas supply has been guaranteed, the city eliminated 35 tons of steam / hour and below the coal-fired boilers.

2, increase the coal management and control efforts. Coal infrared video monitoring devices to increase coal quality sampling efforts, to retain the blast furnace coal-fired boilers to be installed, Hebei coal to meet local standards "Industrial and domestic fuel coal" (DB13 / 208102014) non-coal power generation industry quality indicators .

3, strict new boiler access. Ⅲ class urban area and high-pollution fuel combustion zone ban municipal government designated a ban on new coal-fired boiler, a citywide ban on new 35 steam tons / hour and coal-fired boilers, the new 35 steam tons / hour of coal-fired boilers must in line with the municipal government of central heating planning or construction of industrial parks planning, energy efficiency reached AQSIQ "energy-saving technology supervision and management procedures boiler (TSGG0002-2010)" requirements, encourage the use of "energy efficient boiler promotion List" reached the level of energy efficiency standards boiler, pollutant emissions to meet emission standards require extremely low.

Gas-fired steam boiler three horizontal wet return back structure WNS series automatic oil, gas steam boiler three horizontal wet return back structure, improve the boiler operating environment, to improve boiler efficiency and service life; all of the flue gas channel is placed in water, the tail with the fin tube condenser and a sound production state designated boilers, pressure vessels manufacturers. Adhere to the people-oriented, science and technology a new development strategy, gathered from a high-quality management, technology, production and management personnel, and laid a solid foundation for the development of enterprises. On the basis of the traditional production based on coal-fired boilers, the establishment of an independent new product design, gas steam boiler using three horizontal wet return back junction have developed a new environmentally friendly coal vaporize boiler, electric boiler manufacturers construct WNS series of automatic oil, oil, electric steam boiler. Gas, electric heating steam boiler, electric heating oil furnace pressure fire tube oil and hot water boiler for hotel central heating, organic heat carrier furnace, stove, second class pressure vessel 15 series, more than 200 standard models. \ Province Heng boiler, the boiler is the designated national R & D to improve the quality of our environment and the survival of boiler replacement products industry to make its due contribution to the provincial Heng Boiler Co., Ltd.

A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .
