The gas-fired hot-water boiler is a kind of hot-water boiler. The gas-fired hot-water boiler uses gas (such as natural gas, liquefied petroleum gas, city gas, biogas, etc.) as fuel, heats water through burners, and provides hot water for living and bathing. The boiler is highly intelligent, fast heating, low noise, and dust-free. It is an economic boiler very suitable for China's national conditions.

Gas-fired heating boilers are also called gas-fired heating boilers, gas-fired heating boilers, etc. gas-fired heating boilers refer to boilers that use gas combustion to heat boiler water so as to meet people's heating needs. They belong to the category of Living boilers. The gas-fired heating boiler usually refers to the gas-fired normal pressure hot water boiler. The gas includes natural gas, liquefied gas, city gas, coke oven gas, biogas, etc.

Atmospheric gas-fired heating boilers do not belong to special equipment boilers. The design, manufacture, installation and use of atmospheric gas-fired heating boilers do not need the supervision of the technical supervision department.

The key components of the gas-fired heating boiler include burner, controller, boiler, water level monitoring, etc. after the gas-fired heating boiler is powered on, the control system starts to detect the water level and furnace wall temperature of the boiler, and the detection is normal. The boiler starts to start the burner to heat the water. When the water temperature reaches the set temperature, the burner stops heating, and the boiler water temperature has reached the pump on temperature (the pump on temperature can be set freely), The boiler starts the hot water circulating pump, the hot water circulates in the heating pipeline system, and the heating purpose is realized through the heat dissipation of radiators (such as radiators, fan coil water heating air conditioners, central air conditioning units, etc.).

According to the applicable types of gas, it is divided into liquefied gas heating boiler, natural gas heating boiler, urban gas heating boiler, biogas heating boiler and coke oven gas heating boiler;

It can be divided into single heating boiler and dual-purpose heating boiler according to the purpose;

According to the installation mode of air supply and exhaust, it is divided into natural air supply and exhaust heating boiler, forced air supply heating boiler and forced exhaust heating boiler;

It is divided into atmospheric gas heating boiler and pressure gas heating boiler according to the structural form.

The fuel of oil fired heating boiler is oil (such as diesel, engine oil, kerosene, etc.), and the fuel of gas-fired heating boiler is gas (such as natural gas, city gas, biogas, liquefied gas, etc.). The heating boiler equipped with gas burner is called gas-fired heating boiler, and the heating boiler equipped with oil burner is called oil-fired heating boiler.

Atmospheric oil gas hot water boiler

1、 Overview

In order to ensure the stability of boiler operation and the safety of people's lives and property, the design, manufacture, installation, use and maintenance of the boiler must be carried out in strict accordance with the requirements of Supervision Regulation on safety technology of atmospheric pressure hot water boilers, jb/t10094-2002 general technical conditions for industrial boilers and jb/t1619-2002 technical conditions for the manufacture of shell boilers.

The boiler model shall be prepared according to jb/t1626-2002 method for preparing industrial boiler model.

2、 Boiler system

Clhs********-85/60 oil fired gas-fired hot water boiler is equipped with an imported burner. The fuel oil is atomized by the burner and burned in the furnace liner under slight positive pressure. The high-temperature flue gas enters the pyrotechnic tube bundle for convective heat exchange after radiating heat in the furnace liner, and then is collected in the upper smoke box and discharged into the large gas through the chimney.

Cwns*******-85/60--yq full-automatic oil and gas-fired hot water boiler is a horizontal three return shell boiler. The fuel is combusted in the furnace liner under slight positive pressure through the burner, and the flue gas enters the flue pipe bundle along the furnace liner through the back burning chamber for convective heat transfer, and then is discharged into the atmosphere through the chimney to the rear smoke box. Hinged movable smoke box doors are used at the front and rear ends for convenient maintenance and overhaul.

This series of boilers are compact in structure and convenient in installation and transportation. Each boiler has been debugged in overheated state before leaving the factory, with a high startup rate. Equipped with imported burner, fully automatic program control, high degree of automation, can make the boiler achieve ideal combustion effect.

This series of boilers can be divided into three categories according to their uses: heating furnace, warm water furnace and dual-purpose heating and hot water furnace (hereinafter referred to as dual-purpose furnace).

Heating furnace: used for simple heating.

Warm water stove: the interior is treated with non-toxic anti-corrosion treatment, which can be used for heating and domestic water supply.

Dual purpose boiler: a built-in heat exchange system is added inside to form two independent hot water systems, which can be used for heating and domestic water at the same time.

3、 Installation requirements

General requirements

1. boiler room: the boiler room shall comply with the requirements of gb50041 code for design of boiler rooms. For the foundation, the ground shall be compacted with lime soil and poured with smooth concrete. The thickness of the foundation shall be determined by the designer according to the soil quality of the user.

2. boiler installation shall comply with relevant national standards, code for construction and acceptance of atmospheric hot water boiler installation engineering.

3. the boiler is strictly prohibited to burn gasoline and light diesel and heavy diesel mixed with gasoline in any proportion. Before installation and use, carefully read and understand the burner installation and operation instructions provided with the burner.

4. precautions:

1) The boiler installation site must have 380/50 (v/hz) power supply with sufficient capacity and enough operation and maintenance space.

2) The boiler installation site shall be relatively dry, which can ensure 24-hour ventilation and meet the fire-fighting conditions; Do not be close to inflammables and explosives; It is forbidden to install in wet, open air and strong acid and alkali corrosive places.

3) There shall be no high-voltage strong current interference source in the boiler installation site to avoid wrong action of the control system
