What is a hot water boiler?

Hot water boiler is a kind of thermal energy equipment that uses natural gas, oil, biomass, etc. as fuel to heat water to a rated temperature. It is widely used in heating, bathing and domestic hot water in hotels, schools, guesthouses, communities and other enterprises. There are many types of hot water boiler brands in the market. This article takes ZOZEN hot water boiler as an example to introduce the classification of hot water boilers and common low nitrogen hot water boilers.

Classification of hot water boilers

According to the purpose: domestic hot water boiler, hotel hot water boiler, central heating hot water boiler, etc.;

According to fuel: gas-fired hot water boiler, oil-fired hot water boiler, biomass-fired hot water boiler, coal-fired hot water boiler, etc.;

According to pressure: atmospheric pressure hot water boiler, pressure-bearing hot water boiler;

According to body type: horizontal hot water boiler, vertical hot water boiler...

Common low nitrogen hot water boilers

1. oil-fired and gas-fired hot water boiler

Oil-fired and gas-fired hot water boilers are a common type today. ZOZEN oil-fired and gas-fired boilers are designed with a large combustion chamber and feature fully automatic operation to achieve high efficiency, energy saving, and safe operation; the boiler body is made of high-quality aluminum silicate fiber, Refractory mud is used for heat preservation, and the temperature of the furnace body is controlled below 45 °C to effectively control heat loss.

WNS series hot water boiler: 0.7-14MW normal pressure/0.7-1.25MPa

SZS series hot water boiler: 7-116MW 1-1.6MPa

2. Biomass hot water boilers

ZOZEN biomass hot water boiler has a wide range of fuel applicability and can be used for biomass pellets, wood chips, palm shell, straw and other fuels; at the same time, ZOZEN boiler reasonably designs relevant structures according to different fuel characteristics to ensure high efficiency, energy saving and stable operation of the boiler; Solve the problems of ash, coking, wear, arch before burning, burning hopper and so on.

SZL series hot water boiler: 2.8-29MW 1-1.25MPa

DZL series hot water boiler: 14-70MW 1-1.6MPa

DHL series hot water boiler: 29-116MW 1.25-1.6MPa

3. Circulating fluidized bed hot water boiler

Circulating fluidized bed hot water boiler is a mature clean combustion technology with high efficiency and low pollution. It can burn various biomass fuels, coal, gangue, etc. It belongs to low temperature combustion, so the emission of nitrogen oxides is low, only about 100mg/Nm³. It can realize direct desulfurization in the combustion process, and the desulfurization efficiency is high. In addition, the technical equipment is economical and simple, and the initial investment and operating cost of desulfurization are relatively low. It is a relatively common boiler furnace type in China.

SHX series circulating fluidized bed boiler: 7-58MW 1-1.6MPa

DHX series circulating fluidized bed boiler: 58-116MW 1.25-1.6MPa
