How to choose a burner and what is the difference between a burner and a burner

How should I choose a burner?

For large and medium-sized equipment such as burners, the sophistication of equipment plays a vital role in the improvement and stability of the production capacity of the enterprise, so the selection of burner equipment is divided into imported and domestic. I believe that for everyone, imported equipment is more satisfying in terms of product quality and operational stability, but the quality of imported equipment is relatively high, and it does not represent the quality and performance of the product. The domestic brand burner can also meet the requirements of the imported burner, and it can also be accepted by many enterprises.

Therefore, enterprise users need to choose according to their own enterprises when choosing combustion equipment.

Nowadays, there are many domestic brands that do not belong to imported products in terms of product quality, and the imported equipment used in the core configuration components, and the rest of the domestic ones, so that the quality is not inferior to imported products at the same time, which is the new choice of many domestic enterprise users.

In addition to the above reasons that need to be considered, in response to the current global pollution situation, in response to national environmental protection requirements, between energy-saving burner equipment and environmentally friendly burner equipment, we must choose carefully. On the one hand, the pollutant emission standards should not exceed the national standards, and on the other hand, it is necessary to keep the fuel completely burned and never wasted.

First, the choice of the manufacturer The burner is mainly imported or domestic burner. The main characteristics of the imported burner are mature technology, high degree of refinement, high efficiency and environmental protection, high safety and environmental protection, high safety and stable system, but at the same time, high quality. The domestic burner system is immature, poor stability, low thermal efficiency, but low.

At present, the main brands of imported burners are: Italian Riello, Italian Black & Decker, General, Italian Flange, Italian and other highs, American Maxson, German Weiso, British Liwei, Finland Olin and so on.

The main brands of domestic burners are: Zhejiang Baxter, Orite, Baites and so on. We generally recommend the use of imported burners: mainly considering stability, safety, high efficiency and other factors.

2. Fuel selection burners are mainly divided into different fuels burned: Take Riello burners as an example.

1. Fuel oil series: light oil such as Ria Lu REG series, heavy oil such as Ria Road RN series;

2. Gas series: a section of gas series such as Ria Road; Two Sections of RS M Series as Fierce as Riello ;

3. Dual-fuel (oil and gas) series: such as Riello RLS series ENNW EMMW series; Users can make a choice according to their own economic strength and fuel**.

3. Model selection The method of model selection is mainly to select the thermal power of the burner according to the thermal power of the boiler (the model is determined by the thermal power of the burner).

1. The calculation method of burner power: burner power = boiler power Thermal efficiency The burner model is determined, and the pressure and flow rate suitable for the burner should be selected according to the actual needs.

Gas burner: required gas flow rate [m3n h]=(burner power [kw] gas calorific value mj m3n]; Fuel burner: Fuel flow demand [kg h] = (burner power [kw] fuel calorific value [mj kg].

2. Select valve groups for gas and dual-fuel burners (mainly for gas boilers):

Use the valve block selection table to select a valve block of sufficient diameter, please note that the value of the valve block selection table is based on the data when the boiler back pressure is 0. When selecting a valve block, the actual gas pressure must be subtracted from the boiler back pressure to select the valve block. The gas in the valve block selection table is natural gas.

3. Check the connection size of the burner, especially the burner head needs to fit the boiler, and the length of the burner head should be 10-20 mm above the fire-resistant throat in the boiler. Check the flame size in the flame size chart, making sure that the flame does not touch the furnace wall.

To sum up, customers consider the scientific selection method of oil-fired gas boilers according to their own actual conditions to ensure that they can purchase oil-fired gas boilers with high efficiency, high energy-saving stability and suitable for themselves.

First, you need to be clear about what kind of gas energy your kiln uses, generally natural gas, liquefied petroleum gas, coal gas, etc., and don't confuse them. The calorific value of different gases is different, that is, the temperature reached is different. Generally their calorific value is shown below:

Common gas calorific value.

At the same time, the internal structure of the burner will be different depending on the gas, so it is important to be clear about the gas to be used at the beginning.

Second, you need to know how big the burner (burner) you want, the bigger the burner (burner), the more power. Generally, we will ask customers how many thousands of calories or how many kilowatts (power unit) of burners (burners), and each manufacturer will basically have their own burner (burner) models and specifications.

This topic is very big, I will say a few points for reference: 1. Your equipment positioning: high-end will choose imported, full-featured ones, of course, the best will be high, and the quality will be relatively good; Second, the type of your device:

For example, water heaters, any brand series can be basically used, and such as furnaces, the main brands such as Belden and Olympea are selected; 3. The fuel you choose: diesel, heavy oil, liquefied gas, natural gas, etc., the burner category of different fuel choices is different; Fourth, it is the maximum thermal power converted into the thermal efficiency required by your equipment, and generally divide the maximum thermal power you need by the value obtained to select the burner with the maximum power value in the nameplate identification. It's just a rough pick.

The actual output of the burner is related to the environment (temperature, altitude, etc.), the combustion chamber structure, the flue, the gas turbine, and the gas pressure, valve selection, and so on. The selection of the burner will affect the subsequent adjustment and use, and it will not be able to be used in serious cases; Fifth, your equipment is new equipment or old equipment: the old equipment directly refers to the original, there is no basis to see the diameter of the original equipment installation hole, the location and space around the center of the installation hole, so that the selected burner can be installed and debugged and maintained.

The selection of fuel and gas boiler burners should be selected according to the structural characteristics and performance requirements of the boiler body and the fuel characteristics, combined with the user's use conditions. As the combustion equipment of oil and gas boilers, the main functions of the burner are:

1) Provide the oil or gas required by the boiler, and choose the oil atomization method for the oil fuel to increase the fuel and air.

Contact area. For gaseous fuels, the combustion method should also be selected.

2) Supply the necessary air for combustion, and realize the full mixing of air with oil mist or gas to ensure complete combustion.

3) Ensure that the ignition is fast and the combustion is stable.

4) Realize the automatic control of program ignition and combustion process.

To choose the right burner, you need to know the required power, gas pressure, wind pressure, NOx emissions after combustion, etc

How to choose the type of burner depends on the amount of power you need, the gas air pressure, and the nitrogen emission during combustion.

A burner is a device that causes fuel and air to be sprayed in a certain way for mixed (or mixed ejection) combustion. According to the type and application field, the burner is divided into industrial burners, burners, civil burners, and special burners. In the broad concept of burners, household water heaters, gas stoves, and even lighters can be considered as a type of burner.

According to its working principle, a burner can be defined as a device that converts a substance into heat energy through a chemical reaction of combustion – that is, air and fuel are mixed in appropriate proportions through a premix device to make them fully combustion.

Burners can be classified in a variety of ways according to their different properties. According to the fuel method, it is divided into oil burner, gas burner and dual fuel burner. Where:

In specific applications, oil burners will be divided into light oil burners, heavy oil burners, etc.; Gas burners are divided into natural gas burners, city gas burners, etc.

According to the combustion control mode of the burner, it is divided into: single-stage fire burner, double-stage fire burner, proportional adjustment burner. According to the fuel atomization method, it is divided into:

mechanical atomization burner, medium atomization burner; According to the structure, it is divided into: integral burner and split burner. Among them, the split burner is mainly used in industrial production, and its main feature is that the combustion system, air supply system, control system, etc. are decomposed and installed, and this kind of machine is mainly suitable for large equipment or special working environments such as high temperature.

There is no difference, only the name is different.

The difference between the burner and the burner, the burner is generally called the burner in China, and the combustion control system can be split and installed according to the actual use, and the burner is generally called the integrated burner, which is an integrated small combustion system with its own combustion accessories such as fans.

Now these two names basically have one meaning, both refer to the burner, the foreign English name burnner, when translated into Chinese, the burner burner is basically a meaning. So it makes no difference. For example:

The Weiru burner and the Weiru burner are the same brand of burners.
