Main contents of boiler energy efficiency test:

1. Boiler thermal efficiency test: a) determination of boiler evaporation; b) boiler excess air coefficient detection; c) exhaust smoke temperature detection; d) fuel combustion efficiency test; e) boiler thermal efficiency test; f) fuel consumption; g) Steam to coal ratio.

2. Boiler new product stereotyped energy efficiency test: Determine whether the boiler thermal performance indicators are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.

3. Boiler operation adjustment test: Determine the most economical operation mode of the boiler and identify defects in the boiler operation. Such as boiler maximum load, boiler minimum load, fuel requirements, economic load, reasonable exhaust gas temperature, optimum wind coal ratio, excess air ratio, secondary air ratio and so on.

4. Comparative test of thermal performance before and after boiler reform: changes in evaporation, effects of combustion, thermal efficiency of boilers, etc.

5, fuel industry analysis, elemental analysis: to judge the quality of oil, gas and other fuels, easy for enterprises to control the quality of fuel into the plant.

6, water quality testing, scale analysis: determine the quality of water, control the boiler water indicators to prevent boiler fouling.

March 22 to 23, Ganzhou City, Jiangxi Province Bureau of Quality Supervision established party leadership team, the progress of the 2018 phase-out of coal-fired boilers to conduct random work. Leading group led by Liu Ping, deputy director of Ganzhou City, Municipal Quality Supervision Bureau, the Municipal Industry and Information Commission, the Municipal Environmental Protection Bureau and the Municipal Development and Reform Commission composed of four departments jointly checks group within Xinfeng County of Ganzhou City, Nankang District, Jiangxi counties and carried out spot checks Yudu County coal-fired boilers working-out of a total of 17 companies.

Sampling results show that 17 companies, more than 10 companies to complete phase-out of coal-fired boilers, the other seven unfinished business executives also said that this year will be to complete the rectification work before December 20.

In this sampling event, checks the group also proposed rectification direction of the coal-fired boilers for local authorities: by strengthening the policy advocacy, strengthening inter-site inspectors guidance and strengthen departmental interaction, the three parties work together to ensure the timely completion of this non-compliance within Ganzhou coal-fired boiler out of the task.

Boiler boiler should be classified according to which of several energy conversion device is a way, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Many types of boilers, we like how to categorize them? Here Jinhe company you explain one by one! Many classification of the boiler, the boiler can be divided according to use, can be divided according to the structure, the type of fuel boilers, but also you can press the water cycle in the form of pressure classification. It can be used as boiler thermal power boilers and heating boilers. Power boiler comprising a power station boilers, marine boilers and boiler locomotive, corresponding to power generation, marine, and locomotive power dynamic. Heating boiler comprising a steam boilers, coal fired double drums chain grate hot water boilers, hot tube boiler, stove and the heating medium heating furnace, to give a corresponding steam, hot water. Hot air and the heating medium and the like. Boiler by the structure, divided into fire tube boiler and water tube boilers. Fire-tube boiler, including vertical and horizontal boiler boiler, water tube boilers and water tube boilers including horizontal, vertical, water tube boilers. By species classified as boiler fuel gas-fired boiler, oil-fired boiler and upgrade technical gas boiler and gas boiler, furnace oil and gas alternative --- pulverized coal boilers, gas boilers and other dual-use. Combustion gas boiler can be divided into layers by firing boiler, in fluidized bed boilers and combustion chambers. The latest fuel alcohol-based fuel boiler, he will greatly reduce the pollution of the atmosphere of a gas boiler. Evaporation of less than 20t / h is called a small boiler, evaporation to 75t / h is referred to as large boilers, evaporation of medium-boiler referred interposed therebetween.

What precautions when using industrial boilers? Mainly to provide the industrial production of energy and other power production in order to maintain a power device of its manufacturing operations, one of which is a major steam-powered electricity or gas to maintain the use of industrial boilers, another is based on coal providing power to maintain the operation of the production as raw materials by recycling waste heat boiler traditional industries, it is widely used in industrial production. So, when people use professional industrial boilers need to pay attention to what matters it? First, the operating personnel in the use of industrial boilers operate not only need to have the relevant knowledge and proficiency in operating skills, but also in the operation of the boiler should be run strictly prohibited without leaving their jobs so that the boiler is in a state of neglect, reduce accidents caused by the furnace excessive pressure or pot water level is too high and so on. Second, the staff undergo a rigorous technical evaluation before the relevant professional departments should be adjusted to improve the working pressure in the industrial boilers, pressure gauge and a safety valve to avoid common cause failures industrial boiler overpressure phenomenon appeared to mislead the operator allowed to adjust make mistakes, we should also strengthen the operational skills related to operating personnel so that timely treatment is not a normal phenomenon during boiler operation. Third, before use should be fully checked industrial boilers and boiler configuration check voltage is in the normal current value, the structure of the boiler to avoid unreasonable or poor welding quality and safety accessories related failures caused by the occurrence of industrial boiler runtime accident while before using the boiler should also be adequate treatment in order to be able to reduce accidents during the operation running. These are the three issues of professional industrial boilers in the use of the relevant operators should be noted, strict attention to its use handling precautions can effectively avoid improper operation caused an accident when using a boiler, while improving industrial production to a certain extent efficiency, selected first-class industrial boiler manufacturers can better protect their quality in the selection of industrial boilers used in industrial production.
