heavy oil using a boiler

Fuel gas using a boiler heat losses are mainly chemical heat loss q2 and q3 loss of incomplete combustion heat loss q5. Exhaust gas boiler q2 loss is generally about 5 to 8 percent, chemical incomplete combustion loss of about 0.5% q3, q5 heat loss of 1% to 3%. Because almost no ash after combustion of the fuel gas, and no mechanical incomplete combustion of solid fuels and, therefore, no need for oil or gas boiler counted mechanical incomplete combustion ash heat loss and heat loss, i.e., q4 = q6 = 0. In all heat losses, heat losses q2 represent an important proportion, 70% to 80% of the total loss. Therefore, the main heat losses of fuel gas-fired boiler flue gas heat loss is q2. [Doyo | page]

Jilin Province is located in northeast China, colder winter. Jilin Province is the autumn and winter air pollution problems are most acute period is the peak period of fog and haze. To reduce the frequency of occurrence of fog and haze, to reduce emissions of air pollution, according to "implement the central Jilin Province Environmental Protection Inspector feedback reform program", Jilin cities to carry out the 2018 autumn and winter special law enforcement inspection of non-electric coal-fired using a boilers. Specific implementation of the program as follows.

2018 autumn and winter non-electric coal-fired boiler special law enforcement inspection action plan

First, the objectives

Through the "2018 autumn and winter special law enforcement inspection of non-electric boiler coal" action to further increase the intensity of emissions of air pollutants such as excessive penalties for violations combat, urge local governments and environmental protection departments to effectively implement the "Jilin province to implement the central environmental protection inspector feedback reform program, "Forced enterprises to speed up 10 tons of steam coal-fired boilers small and out of more than 20 tons of steam and non-electric coal-fired boiler pollution control facilities upgrade progress to ensure stable discharge standards.

Second, the scope of the inspection

Cities (prefectures) and Changbai Mountain Administrative Committee, Meihekou, Gongzhuling City, Hunchun.

Third, check the time

2018 Nian September 1 to November 30.

Fourth, inspection methods and content

Cities (prefectures) and counties under the jurisdiction of Changbai Mountain Administrative Committee to set up inspection teams to units in the area to take a cross peer review mode, Meihekou, Gongzhuling City, Hunchun to self-oriented.

The principle of mutual cross-check on the environmental violations found, the city's environmental protection departments at all levels in accordance with "should check to make investigation, should make a fine penalty, should be moved to make-shift" of errant given time out of the boiler, not dust removal facilities renovation no construction of desulphurization facilities are not required to install, networking, using automatic monitoring equipment, excessive discharge of pollutants and other acts take full advantage of "environmental law" and supporting measures to implement daily basis penalties, limited production shutdown, sequestration, administrative detention measures to deal with.

Focus on examination of the following:

(A) the progress of 10 tons of steam coal-fired boilers little out of work. According to "implement the central Jilin Province Environmental Protection Inspector feedback reform program," according to the time limit set by local governments, the progress of the phase-out of coal-fired boiler 10 tons of steam since 2014, the province's illegal 1570 newly registered units to be checked.

(B) more than 20 tons of steam coal-fired boiler non-electric dust removal, desulfurization facilities upgrade progress, automatic monitoring equipment installation, networking, usage. By ShengTing 6, July scheduling, the current to complete the rectification stage 717, stage 108 does not start the rectification, the rectification is 277, automatic monitoring equipment table 140 is not installed, the slow progress of the rectification. To complete the transformation around the boiler on-site verification, focusing on inspection facilities dust removal, desulfurization facilities upgrading and installation of automatic monitoring equipment, networking, usage. Percentage being modified, check the current progress of the major transformation of the situation, progress of the project, the time frame for completion, safeguard measures taken, it requires the use of boiler units issued commitments. For failure to start the transformation, to identify the main reason for not starting. If we do not transform the way in which the pin number to take all necessary construction and renovation tasks must be completed in accordance with the requirements of 30 September.

(C) boiler emissions standards. To install automatic monitoring equipment to monitor them than to confirm the validity of the data. For failure to require the installation of automatic monitoring equipment, shall be punished in accordance with relevant laws and regulations, at the same time supervisory monitoring, to determine whether to achieve a stable discharge standards.

Fall and winter heating season is the peak of Jilin Province, to ensure the normal heating units, we must also pay attention to boiler problems in the process of environmental protection. For the high-emission, high-polluting coal-fired boiler and other fuel boiler, to be banned or corrective action.

Burner What are the main components of the using a boiler burner, by definition, refers to the use of the burner on the boiler, boiler fuel gas-fired boiler burner is an important equipment. If the burner on strike, then the boiler will not burn up. Since the boiler burner is so important, we have to look at it part of it. See below: 1 air supply system. Function into the air supply system is to a certain wind speed and amount of air to the combustion chamber, its main components are: a housing, fan motors, fan impeller, air guns fire tube, damper controller, damper baffle, a cam adjustment mechanism, diffusion plate. 2. The ignition system. The function of the ignition system ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. Flame length, taper angle, the shape of the design according to user requirements. 3. Monitoring System. Function monitoring system is to ensure that the burner safe and stable operation, the main components are flame detectors, pressure monitors, temperature monitors and the like. 4. The fuel system. Function of the fuel system is to ensure that the desired fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The gas burner mainly a filter, pressure regulator, solenoid valve, and then firing solenoid valve, the fuel valve. The electronic control system. Electronic control system is the command center and the focal point for the above system, the main control element is a control box, for different burner with a different programmer, common control box has: LFL series, LAL series, LOA series, LGB series the main difference is the time of each different program steps.

Burning fuel oil (heavy oil), natural gas, dry gas, and coal gas using a boilers, in the actual operation of the fuel is difficult to completely avoid the explosion concentration limit of the range appear, especially when the ignition, due to improper operation occurs so easily hearth furnace deflagration or explosion.
